Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583090, here are decompositions:

3 + 31583087 = 31583090
43 + 31583047 = 31583090
67 + 31583023 = 31583090
109 + 31582981 = 31583090
139 + 31582951 = 31583090
193 + 31582897 = 31583090
199 + 31582891 = 31583090
271 + 31582819 = 31583090

Showing the first eight; more decompositions exist.
