Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583306, here are decompositions:

37 + 31583269 = 31583306
283 + 31583023 = 31583306
409 + 31582897 = 31583306
487 + 31582819 = 31583306
577 + 31582729 = 31583306
673 + 31582633 = 31583306
907 + 31582399 = 31583306
1039 + 31582267 = 31583306

Showing the first eight; more decompositions exist.
