Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592002, here are decompositions:

3 + 31591999 = 31592002
5 + 31591997 = 31592002
23 + 31591979 = 31592002
89 + 31591913 = 31592002
251 + 31591751 = 31592002
263 + 31591739 = 31592002
269 + 31591733 = 31592002
353 + 31591649 = 31592002

Showing the first eight; more decompositions exist.
