Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599526, here are decompositions:

137 + 31599389 = 31599526
173 + 31599353 = 31599526
353 + 31599173 = 31599526
467 + 31599059 = 31599526
587 + 31598939 = 31599526
593 + 31598933 = 31599526
599 + 31598927 = 31599526
617 + 31598909 = 31599526

Showing the first eight; more decompositions exist.
