Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445592, here are decompositions:

5 + 31445587 = 31445592
19 + 31445573 = 31445592
53 + 31445539 = 31445592
103 + 31445489 = 31445592
149 + 31445443 = 31445592
163 + 31445429 = 31445592
173 + 31445419 = 31445592
223 + 31445369 = 31445592

Showing the first eight; more decompositions exist.
