Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582976, here are decompositions:

79 + 31582897 = 31582976
157 + 31582819 = 31582976
199 + 31582777 = 31582976
349 + 31582627 = 31582976
367 + 31582609 = 31582976
463 + 31582513 = 31582976
487 + 31582489 = 31582976
577 + 31582399 = 31582976

Showing the first eight; more decompositions exist.
