Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600664, here are decompositions:

211 + 31600453 = 31600664
223 + 31600441 = 31600664
241 + 31600423 = 31600664
307 + 31600357 = 31600664
331 + 31600333 = 31600664
373 + 31600291 = 31600664
463 + 31600201 = 31600664
547 + 31600117 = 31600664

Showing the first eight; more decompositions exist.
