Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522374, here are decompositions:

11 + 31522363 = 31522374
17 + 31522357 = 31522374
43 + 31522331 = 31522374
47 + 31522327 = 31522374
61 + 31522313 = 31522374
97 + 31522277 = 31522374
127 + 31522247 = 31522374
131 + 31522243 = 31522374

Showing the first eight; more decompositions exist.
