Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557052, here are decompositions:

29 + 31557023 = 31557052
41 + 31557011 = 31557052
113 + 31556939 = 31557052
239 + 31556813 = 31557052
281 + 31556771 = 31557052
311 + 31556741 = 31557052
563 + 31556489 = 31557052
743 + 31556309 = 31557052

Showing the first eight; more decompositions exist.
