Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475074, here are decompositions:

3 + 31475071 = 31475074
5 + 31475069 = 31475074
311 + 31474763 = 31475074
353 + 31474721 = 31475074
383 + 31474691 = 31475074
401 + 31474673 = 31475074
503 + 31474571 = 31475074
593 + 31474481 = 31475074

Showing the first eight; more decompositions exist.
