Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482950, here are decompositions:

3 + 31482947 = 31482950
43 + 31482907 = 31482950
61 + 31482889 = 31482950
127 + 31482823 = 31482950
151 + 31482799 = 31482950
241 + 31482709 = 31482950
283 + 31482667 = 31482950
307 + 31482643 = 31482950

Showing the first eight; more decompositions exist.
