Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590824, here are decompositions:

61 + 31590763 = 31590824
157 + 31590667 = 31590824
193 + 31590631 = 31590824
241 + 31590583 = 31590824
337 + 31590487 = 31590824
373 + 31590451 = 31590824
547 + 31590277 = 31590824
613 + 31590211 = 31590824

Showing the first eight; more decompositions exist.
