Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529544, here are decompositions:

  • 5 + 31529539 = 31529544
  • 23 + 31529521 = 31529544
  • 37 + 31529507 = 31529544
  • 73 + 31529471 = 31529544
  • 97 + 31529447 = 31529544
  • 113 + 31529431 = 31529544
  • 131 + 31529413 = 31529544
  • 191 + 31529353 = 31529544

Showing the first eight; more decompositions exist.
