Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582382, here are decompositions:

61 + 31582321 = 31582382
199 + 31582183 = 31582382
211 + 31582171 = 31582382
379 + 31582003 = 31582382
409 + 31581973 = 31582382
421 + 31581961 = 31582382
499 + 31581883 = 31582382
523 + 31581859 = 31582382

Showing the first eight; more decompositions exist.
