Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583122, here are decompositions:

41 + 31583081 = 31583122
71 + 31583051 = 31583122
89 + 31583033 = 31583122
173 + 31582949 = 31583122
191 + 31582931 = 31583122
383 + 31582739 = 31583122
443 + 31582679 = 31583122
449 + 31582673 = 31583122

Showing the first eight; more decompositions exist.
