Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494604, here are decompositions:

23 + 31494581 = 31494604
101 + 31494503 = 31494604
107 + 31494497 = 31494604
137 + 31494467 = 31494604
173 + 31494431 = 31494604
257 + 31494347 = 31494604
311 + 31494293 = 31494604
347 + 31494257 = 31494604

Showing the first eight; more decompositions exist.
