Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493674, here are decompositions:

101 + 31493573 = 31493674
197 + 31493477 = 31493674
227 + 31493447 = 31493674
353 + 31493321 = 31493674
383 + 31493291 = 31493674
503 + 31493171 = 31493674
521 + 31493153 = 31493674
617 + 31493057 = 31493674

Showing the first eight; more decompositions exist.
