Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583150, here are decompositions:

3 + 31583147 = 31583150
13 + 31583137 = 31583150
19 + 31583131 = 31583150
103 + 31583047 = 31583150
127 + 31583023 = 31583150
199 + 31582951 = 31583150
331 + 31582819 = 31583150
373 + 31582777 = 31583150

Showing the first eight; more decompositions exist.
