Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590884, here are decompositions:

7 + 31590877 = 31590884
37 + 31590847 = 31590884
43 + 31590841 = 31590884
151 + 31590733 = 31590884
313 + 31590571 = 31590884
397 + 31590487 = 31590884
421 + 31590463 = 31590884
433 + 31590451 = 31590884

Showing the first eight; more decompositions exist.
