Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557058, here are decompositions:

47 + 31557011 = 31557058
101 + 31556957 = 31557058
149 + 31556909 = 31557058
311 + 31556747 = 31557058
317 + 31556741 = 31557058
419 + 31556639 = 31557058
521 + 31556537 = 31557058
557 + 31556501 = 31557058

Showing the first eight; more decompositions exist.
