Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597316, here are decompositions:

73 + 31597243 = 31597316
103 + 31597213 = 31597316
139 + 31597177 = 31597316
313 + 31597003 = 31597316
367 + 31596949 = 31597316
409 + 31596907 = 31597316
433 + 31596883 = 31597316
523 + 31596793 = 31597316

Showing the first eight; more decompositions exist.
