Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583590, here are decompositions:

29 + 31583561 = 31583590
41 + 31583549 = 31583590
83 + 31583507 = 31583590
113 + 31583477 = 31583590
167 + 31583423 = 31583590
239 + 31583351 = 31583590
419 + 31583171 = 31583590
431 + 31583159 = 31583590

Showing the first eight; more decompositions exist.
