Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582844, here are decompositions:

67 + 31582777 = 31582844
211 + 31582633 = 31582844
313 + 31582531 = 31582844
331 + 31582513 = 31582844
373 + 31582471 = 31582844
523 + 31582321 = 31582844
577 + 31582267 = 31582844
661 + 31582183 = 31582844

Showing the first eight; more decompositions exist.
