Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607570, here are decompositions:

19 + 31607551 = 31607570
67 + 31607503 = 31607570
97 + 31607473 = 31607570
109 + 31607461 = 31607570
229 + 31607341 = 31607570
271 + 31607299 = 31607570
277 + 31607293 = 31607570
307 + 31607263 = 31607570

Showing the first eight; more decompositions exist.
