Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75380, here are decompositions:

  • 3 + 75377 = 75380
  • 13 + 75367 = 75380
  • 43 + 75337 = 75380
  • 73 + 75307 = 75380
  • 103 + 75277 = 75380
  • 127 + 75253 = 75380
  • 157 + 75223 = 75380
  • 163 + 75217 = 75380

Showing the first eight; more decompositions exist.
