Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514590, here are decompositions:

  • 11 + 31514579 = 31514590
  • 17 + 31514573 = 31514590
  • 53 + 31514537 = 31514590
  • 113 + 31514477 = 31514590
  • 167 + 31514423 = 31514590
  • 281 + 31514309 = 31514590
  • 293 + 31514297 = 31514590
  • 431 + 31514159 = 31514590

Showing the first eight; more decompositions exist.
