Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544738, here are decompositions:

  • 19 + 31544719 = 31544738
  • 151 + 31544587 = 31544738
  • 229 + 31544509 = 31544738
  • 367 + 31544371 = 31544738
  • 457 + 31544281 = 31544738
  • 571 + 31544167 = 31544738
  • 607 + 31544131 = 31544738
  • 661 + 31544077 = 31544738

Showing the first eight; more decompositions exist.
