Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583054, here are decompositions:

3 + 31583051 = 31583054
7 + 31583047 = 31583054
31 + 31583023 = 31583054
73 + 31582981 = 31583054
103 + 31582951 = 31583054
157 + 31582897 = 31583054
163 + 31582891 = 31583054
277 + 31582777 = 31583054

Showing the first eight; more decompositions exist.
