Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496442, here are decompositions:

13 + 31496429 = 31496442
23 + 31496419 = 31496442
53 + 31496389 = 31496442
71 + 31496371 = 31496442
73 + 31496369 = 31496442
113 + 31496329 = 31496442
149 + 31496293 = 31496442
179 + 31496263 = 31496442

Showing the first eight; more decompositions exist.
