Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574584, here are decompositions:

  • 53 + 31574531 = 31574584
  • 131 + 31574453 = 31574584
  • 257 + 31574327 = 31574584
  • 281 + 31574303 = 31574584
  • 383 + 31574201 = 31574584
  • 491 + 31574093 = 31574584
  • 563 + 31574021 = 31574584
  • 617 + 31573967 = 31574584

Showing the first eight; more decompositions exist.
