Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522446, here are decompositions:

5 + 31522441 = 31522446
13 + 31522433 = 31522446
73 + 31522373 = 31522446
83 + 31522363 = 31522446
89 + 31522357 = 31522446
107 + 31522339 = 31522446
149 + 31522297 = 31522446
199 + 31522247 = 31522446

Showing the first eight; more decompositions exist.
