Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526442, here are decompositions:

11 + 31526431 = 31526442
19 + 31526423 = 31526442
23 + 31526419 = 31526442
53 + 31526389 = 31526442
71 + 31526371 = 31526442
83 + 31526359 = 31526442
229 + 31526213 = 31526442
251 + 31526191 = 31526442

Showing the first eight; more decompositions exist.
