Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584380, here are decompositions:

  • 37 + 2147584343 = 2147584380
  • 59 + 2147584321 = 2147584380
  • 103 + 2147584277 = 2147584380
  • 127 + 2147584253 = 2147584380
  • 131 + 2147584249 = 2147584380
  • 199 + 2147584181 = 2147584380
  • 223 + 2147584157 = 2147584380
  • 257 + 2147584123 = 2147584380

Showing the first eight; more decompositions exist.
