Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494632, here are decompositions:

79 + 31494553 = 31494632
163 + 31494469 = 31494632
193 + 31494439 = 31494632
331 + 31494301 = 31494632
541 + 31494091 = 31494632
643 + 31493989 = 31494632
691 + 31493941 = 31494632
733 + 31493899 = 31494632

Showing the first eight; more decompositions exist.
