Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583124, here are decompositions:

37 + 31583087 = 31583124
43 + 31583081 = 31583124
73 + 31583051 = 31583124
101 + 31583023 = 31583124
163 + 31582961 = 31583124
173 + 31582951 = 31583124
193 + 31582931 = 31583124
211 + 31582913 = 31583124

Showing the first eight; more decompositions exist.
