Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583612, here are decompositions:

103 + 31583509 = 31583612
163 + 31583449 = 31583612
199 + 31583413 = 31583612
331 + 31583281 = 31583612
631 + 31582981 = 31583612
661 + 31582951 = 31583612
883 + 31582729 = 31583612
1123 + 31582489 = 31583612

Showing the first eight; more decompositions exist.
