Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445496, here are decompositions:

7 + 31445489 = 31445496
37 + 31445459 = 31445496
53 + 31445443 = 31445496
67 + 31445429 = 31445496
79 + 31445417 = 31445496
109 + 31445387 = 31445496
127 + 31445369 = 31445496
139 + 31445357 = 31445496

Showing the first eight; more decompositions exist.
