Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494022, here are decompositions:

23 + 31493999 = 31494022
71 + 31493951 = 31494022
113 + 31493909 = 31494022
233 + 31493789 = 31494022
239 + 31493783 = 31494022
311 + 31493711 = 31494022
449 + 31493573 = 31494022
503 + 31493519 = 31494022

Showing the first eight; more decompositions exist.
