Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493752, here are decompositions:

41 + 31493711 = 31493752
179 + 31493573 = 31493752
233 + 31493519 = 31493752
239 + 31493513 = 31493752
431 + 31493321 = 31493752
461 + 31493291 = 31493752
503 + 31493249 = 31493752
599 + 31493153 = 31493752

Showing the first eight; more decompositions exist.
