Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600798, here are decompositions:

179 + 31600619 = 31600798
269 + 31600529 = 31600798
347 + 31600451 = 31600798
389 + 31600409 = 31600798
479 + 31600319 = 31600798
491 + 31600307 = 31600798
521 + 31600277 = 31600798
641 + 31600157 = 31600798

Showing the first eight; more decompositions exist.
