Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600700, here are decompositions:

7 + 31600693 = 31600700
31 + 31600669 = 31600700
37 + 31600663 = 31600700
151 + 31600549 = 31600700
277 + 31600423 = 31600700
367 + 31600333 = 31600700
409 + 31600291 = 31600700
421 + 31600279 = 31600700

Showing the first eight; more decompositions exist.
