Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557326, here are decompositions:

43 + 31557283 = 31557326
79 + 31557247 = 31557326
109 + 31557217 = 31557326
127 + 31557199 = 31557326
139 + 31557187 = 31557326
313 + 31557013 = 31557326
457 + 31556869 = 31557326
499 + 31556827 = 31557326

Showing the first eight; more decompositions exist.
