Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475194, here are decompositions:

5 + 31475189 = 31475194
53 + 31475141 = 31475194
83 + 31475111 = 31475194
197 + 31474997 = 31475194
263 + 31474931 = 31475194
431 + 31474763 = 31475194
461 + 31474733 = 31475194
503 + 31474691 = 31475194

Showing the first eight; more decompositions exist.
