Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494328, here are decompositions:

71 + 31494257 = 31494328
149 + 31494179 = 31494328
167 + 31494161 = 31494328
401 + 31493927 = 31494328
419 + 31493909 = 31494328
617 + 31493711 = 31494328
809 + 31493519 = 31494328
881 + 31493447 = 31494328

Showing the first eight; more decompositions exist.
