Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600760, here are decompositions:

7 + 31600753 = 31600760
19 + 31600741 = 31600760
43 + 31600717 = 31600760
67 + 31600693 = 31600760
97 + 31600663 = 31600760
211 + 31600549 = 31600760
229 + 31600531 = 31600760
307 + 31600453 = 31600760

Showing the first eight; more decompositions exist.
