Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562736, here are decompositions:

53 + 31562683 = 31562736
59 + 31562677 = 31562736
109 + 31562627 = 31562736
113 + 31562623 = 31562736
193 + 31562543 = 31562736
269 + 31562467 = 31562736
307 + 31562429 = 31562736
313 + 31562423 = 31562736

Showing the first eight; more decompositions exist.
