Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600690, here are decompositions:

71 + 31600619 = 31600690
167 + 31600523 = 31600690
179 + 31600511 = 31600690
197 + 31600493 = 31600690
239 + 31600451 = 31600690
269 + 31600421 = 31600690
281 + 31600409 = 31600690
383 + 31600307 = 31600690

Showing the first eight; more decompositions exist.
