Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583162, here are decompositions:

3 + 31583159 = 31583162
31 + 31583131 = 31583162
139 + 31583023 = 31583162
181 + 31582981 = 31583162
211 + 31582951 = 31583162
271 + 31582891 = 31583162
433 + 31582729 = 31583162
631 + 31582531 = 31583162

Showing the first eight; more decompositions exist.
