Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582946, here are decompositions:

127 + 31582819 = 31582946
313 + 31582633 = 31582946
337 + 31582609 = 31582946
433 + 31582513 = 31582946
457 + 31582489 = 31582946
547 + 31582399 = 31582946
613 + 31582333 = 31582946
739 + 31582207 = 31582946

Showing the first eight; more decompositions exist.
