Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583094, here are decompositions:

7 + 31583087 = 31583094
13 + 31583081 = 31583094
43 + 31583051 = 31583094
47 + 31583047 = 31583094
61 + 31583033 = 31583094
71 + 31583023 = 31583094
113 + 31582981 = 31583094
157 + 31582937 = 31583094

Showing the first eight; more decompositions exist.
