Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445596, here are decompositions:

23 + 31445573 = 31445596
53 + 31445543 = 31445596
89 + 31445507 = 31445596
107 + 31445489 = 31445596
137 + 31445459 = 31445596
167 + 31445429 = 31445596
179 + 31445417 = 31445596
227 + 31445369 = 31445596

Showing the first eight; more decompositions exist.
