Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574368, here are decompositions:

5 + 31574363 = 31574368
41 + 31574327 = 31574368
71 + 31574297 = 31574368
107 + 31574261 = 31574368
167 + 31574201 = 31574368
269 + 31574099 = 31574368
347 + 31574021 = 31574368
401 + 31573967 = 31574368

Showing the first eight; more decompositions exist.
