Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567402, here are decompositions:

  • 5 + 31567397 = 31567402
  • 89 + 31567313 = 31567402
  • 131 + 31567271 = 31567402
  • 311 + 31567091 = 31567402
  • 353 + 31567049 = 31567402
  • 359 + 31567043 = 31567402
  • 491 + 31566911 = 31567402
  • 563 + 31566839 = 31567402

Showing the first eight; more decompositions exist.
