Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592122, here are decompositions:

71 + 31592051 = 31592122
83 + 31592039 = 31592122
383 + 31591739 = 31592122
389 + 31591733 = 31592122
521 + 31591601 = 31592122
701 + 31591421 = 31592122
773 + 31591349 = 31592122
1061 + 31591061 = 31592122

Showing the first eight; more decompositions exist.
