Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590986, here are decompositions:

43 + 31590943 = 31590986
79 + 31590907 = 31590986
109 + 31590877 = 31590986
139 + 31590847 = 31590986
223 + 31590763 = 31590986
337 + 31590649 = 31590986
397 + 31590589 = 31590986
487 + 31590499 = 31590986

Showing the first eight; more decompositions exist.
