Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494576, here are decompositions:

23 + 31494553 = 31494576
67 + 31494509 = 31494576
73 + 31494503 = 31494576
79 + 31494497 = 31494576
97 + 31494479 = 31494576
107 + 31494469 = 31494576
109 + 31494467 = 31494576
137 + 31494439 = 31494576

Showing the first eight; more decompositions exist.
