Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494606, here are decompositions:

23 + 31494583 = 31494606
53 + 31494553 = 31494606
97 + 31494509 = 31494606
103 + 31494503 = 31494606
109 + 31494497 = 31494606
127 + 31494479 = 31494606
137 + 31494469 = 31494606
139 + 31494467 = 31494606

Showing the first eight; more decompositions exist.
