Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557034, here are decompositions:

11 + 31557023 = 31557034
23 + 31557011 = 31557034
263 + 31556771 = 31557034
293 + 31556741 = 31557034
347 + 31556687 = 31557034
557 + 31556477 = 31557034
617 + 31556417 = 31557034
653 + 31556381 = 31557034

Showing the first eight; more decompositions exist.
