Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607962, here are decompositions:

41 + 31607921 = 31607962
53 + 31607909 = 31607962
59 + 31607903 = 31607962
131 + 31607831 = 31607962
173 + 31607789 = 31607962
179 + 31607783 = 31607962
383 + 31607579 = 31607962
431 + 31607531 = 31607962

Showing the first eight; more decompositions exist.
