Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574962, here are decompositions:

71 + 31574891 = 31574962
101 + 31574861 = 31574962
113 + 31574849 = 31574962
149 + 31574813 = 31574962
239 + 31574723 = 31574962
269 + 31574693 = 31574962
281 + 31574681 = 31574962
431 + 31574531 = 31574962

Showing the first eight; more decompositions exist.
