Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582002, here are decompositions:

5 + 31581997 = 31582002
19 + 31581983 = 31582002
29 + 31581973 = 31582002
41 + 31581961 = 31582002
113 + 31581889 = 31582002
139 + 31581863 = 31582002
223 + 31581779 = 31582002
241 + 31581761 = 31582002

Showing the first eight; more decompositions exist.
