Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529602, here are decompositions:

  • 131 + 31529471 = 31529602
  • 281 + 31529321 = 31529602
  • 353 + 31529249 = 31529602
  • 359 + 31529243 = 31529602
  • 383 + 31529219 = 31529602
  • 389 + 31529213 = 31529602
  • 521 + 31529081 = 31529602
  • 761 + 31528841 = 31529602

Showing the first eight; more decompositions exist.
