Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583126, here are decompositions:

79 + 31583047 = 31583126
103 + 31583023 = 31583126
229 + 31582897 = 31583126
307 + 31582819 = 31583126
349 + 31582777 = 31583126
397 + 31582729 = 31583126
499 + 31582627 = 31583126
613 + 31582513 = 31583126

Showing the first eight; more decompositions exist.
