Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600698, here are decompositions:

5 + 31600693 = 31600698
29 + 31600669 = 31600698
79 + 31600619 = 31600698
149 + 31600549 = 31600698
167 + 31600531 = 31600698
251 + 31600447 = 31600698
257 + 31600441 = 31600698
277 + 31600421 = 31600698

Showing the first eight; more decompositions exist.
