Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522452, here are decompositions:

11 + 31522441 = 31522452
19 + 31522433 = 31522452
41 + 31522411 = 31522452
79 + 31522373 = 31522452
89 + 31522363 = 31522452
113 + 31522339 = 31522452
139 + 31522313 = 31522452
211 + 31522241 = 31522452

Showing the first eight; more decompositions exist.
