Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552102, here are decompositions:

  • 53 + 31552049 = 31552102
  • 83 + 31552019 = 31552102
  • 419 + 31551683 = 31552102
  • 431 + 31551671 = 31552102
  • 503 + 31551599 = 31552102
  • 509 + 31551593 = 31552102
  • 563 + 31551539 = 31552102
  • 599 + 31551503 = 31552102

Showing the first eight; more decompositions exist.
