Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583154, here are decompositions:

7 + 31583147 = 31583154
17 + 31583137 = 31583154
23 + 31583131 = 31583154
67 + 31583087 = 31583154
73 + 31583081 = 31583154
103 + 31583051 = 31583154
107 + 31583047 = 31583154
131 + 31583023 = 31583154

Showing the first eight; more decompositions exist.
