Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582004, here are decompositions:

7 + 31581997 = 31582004
31 + 31581973 = 31582004
43 + 31581961 = 31582004
127 + 31581877 = 31582004
211 + 31581793 = 31582004
331 + 31581673 = 31582004
457 + 31581547 = 31582004
463 + 31581541 = 31582004

Showing the first eight; more decompositions exist.
