Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590458, here are decompositions:

7 + 31590451 = 31590458
37 + 31590421 = 31590458
61 + 31590397 = 31590458
181 + 31590277 = 31590458
271 + 31590187 = 31590458
337 + 31590121 = 31590458
397 + 31590061 = 31590458
421 + 31590037 = 31590458

Showing the first eight; more decompositions exist.
