Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583082, here are decompositions:

31 + 31583051 = 31583082
59 + 31583023 = 31583082
101 + 31582981 = 31583082
131 + 31582951 = 31583082
151 + 31582931 = 31583082
191 + 31582891 = 31583082
263 + 31582819 = 31583082
353 + 31582729 = 31583082

Showing the first eight; more decompositions exist.
