Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557094, here are decompositions:

17 + 31557077 = 31557094
71 + 31557023 = 31557094
83 + 31557011 = 31557094
137 + 31556957 = 31557094
281 + 31556813 = 31557094
347 + 31556747 = 31557094
353 + 31556741 = 31557094
557 + 31556537 = 31557094

Showing the first eight; more decompositions exist.
