Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504486, here are decompositions:

  • 5 + 31504481 = 31504486
  • 47 + 31504439 = 31504486
  • 113 + 31504373 = 31504486
  • 257 + 31504229 = 31504486
  • 353 + 31504133 = 31504486
  • 359 + 31504127 = 31504486
  • 383 + 31504103 = 31504486
  • 389 + 31504097 = 31504486

Showing the first eight; more decompositions exist.
