Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590764, here are decompositions:

31 + 31590733 = 31590764
97 + 31590667 = 31590764
181 + 31590583 = 31590764
193 + 31590571 = 31590764
277 + 31590487 = 31590764
313 + 31590451 = 31590764
367 + 31590397 = 31590764
421 + 31590343 = 31590764

Showing the first eight; more decompositions exist.
