Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480714, here are decompositions:

  • 281 + 31480433 = 31480714
  • 347 + 31480367 = 31480714
  • 653 + 31480061 = 31480714
  • 857 + 31479857 = 31480714
  • 911 + 31479803 = 31480714
  • 971 + 31479743 = 31480714
  • 977 + 31479737 = 31480714
  • 1163 + 31479551 = 31480714

Showing the first eight; more decompositions exist.
