Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583754, here are decompositions:

5 + 31583749 = 31583754
53 + 31583701 = 31583754
61 + 31583693 = 31583754
67 + 31583687 = 31583754
113 + 31583641 = 31583754
127 + 31583627 = 31583754
157 + 31583597 = 31583754
193 + 31583561 = 31583754

Showing the first eight; more decompositions exist.
