Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463422, here are decompositions:

59 + 31463363 = 31463422
101 + 31463321 = 31463422
173 + 31463249 = 31463422
359 + 31463063 = 31463422
443 + 31462979 = 31463422
491 + 31462931 = 31463422
521 + 31462901 = 31463422
773 + 31462649 = 31463422

Showing the first eight; more decompositions exist.
