Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557934, here are decompositions:

3 + 31557931 = 31557934
53 + 31557881 = 31557934
101 + 31557833 = 31557934
173 + 31557761 = 31557934
251 + 31557683 = 31557934
257 + 31557677 = 31557934
263 + 31557671 = 31557934
431 + 31557503 = 31557934

Showing the first eight; more decompositions exist.
