Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588748, here are decompositions:

277 + 31588471 = 31588748
307 + 31588441 = 31588748
349 + 31588399 = 31588748
379 + 31588369 = 31588748
397 + 31588351 = 31588748
547 + 31588201 = 31588748
577 + 31588171 = 31588748
619 + 31588129 = 31588748

Showing the first eight; more decompositions exist.
