Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557334, here are decompositions:

5 + 31557329 = 31557334
41 + 31557293 = 31557334
131 + 31557203 = 31557334
173 + 31557161 = 31557334
257 + 31557077 = 31557334
311 + 31557023 = 31557334
521 + 31556813 = 31557334
563 + 31556771 = 31557334

Showing the first eight; more decompositions exist.
