Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590962, here are decompositions:

3 + 31590959 = 31590962
19 + 31590943 = 31590962
31 + 31590931 = 31590962
199 + 31590763 = 31590962
223 + 31590739 = 31590962
229 + 31590733 = 31590962
313 + 31590649 = 31590962
331 + 31590631 = 31590962

Showing the first eight; more decompositions exist.
