Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583026, here are decompositions:

3 + 31583023 = 31583026
89 + 31582937 = 31583026
113 + 31582913 = 31583026
179 + 31582847 = 31583026
269 + 31582757 = 31583026
347 + 31582679 = 31583026
353 + 31582673 = 31583026
359 + 31582667 = 31583026

Showing the first eight; more decompositions exist.
