Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600668, here are decompositions:

5 + 31600663 = 31600668
137 + 31600531 = 31600668
139 + 31600529 = 31600668
157 + 31600511 = 31600668
227 + 31600441 = 31600668
311 + 31600357 = 31600668
349 + 31600319 = 31600668
367 + 31600301 = 31600668

Showing the first eight; more decompositions exist.
