Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583196, here are decompositions:

37 + 31583159 = 31583196
59 + 31583137 = 31583196
109 + 31583087 = 31583196
149 + 31583047 = 31583196
163 + 31583033 = 31583196
173 + 31583023 = 31583196
283 + 31582913 = 31583196
349 + 31582847 = 31583196

Showing the first eight; more decompositions exist.
