Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577034, here are decompositions:

17 + 31577017 = 31577034
43 + 31576991 = 31577034
67 + 31576967 = 31577034
103 + 31576931 = 31577034
191 + 31576843 = 31577034
257 + 31576777 = 31577034
283 + 31576751 = 31577034
331 + 31576703 = 31577034

Showing the first eight; more decompositions exist.
