Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583002, here are decompositions:

41 + 31582961 = 31583002
53 + 31582949 = 31583002
71 + 31582931 = 31583002
89 + 31582913 = 31583002
179 + 31582823 = 31583002
263 + 31582739 = 31583002
389 + 31582613 = 31583002
401 + 31582601 = 31583002

Showing the first eight; more decompositions exist.
