Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597592, here are decompositions:

43 + 31597549 = 31597592
109 + 31597483 = 31597592
139 + 31597453 = 31597592
181 + 31597411 = 31597592
331 + 31597261 = 31597592
349 + 31597243 = 31597592
379 + 31597213 = 31597592
463 + 31597129 = 31597592

Showing the first eight; more decompositions exist.
