Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493704, here are decompositions:

131 + 31493573 = 31493704
191 + 31493513 = 31493704
227 + 31493477 = 31493704
257 + 31493447 = 31493704
383 + 31493321 = 31493704
503 + 31493201 = 31493704
647 + 31493057 = 31493704
761 + 31492943 = 31493704

Showing the first eight; more decompositions exist.
