Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574362, here are decompositions:

59 + 31574303 = 31574362
101 + 31574261 = 31574362
263 + 31574099 = 31574362
269 + 31574093 = 31574362
401 + 31573961 = 31574362
431 + 31573931 = 31574362
503 + 31573859 = 31574362
509 + 31573853 = 31574362

Showing the first eight; more decompositions exist.
