Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522376, here are decompositions:

3 + 31522373 = 31522376
13 + 31522363 = 31522376
19 + 31522357 = 31522376
37 + 31522339 = 31522376
79 + 31522297 = 31522376
157 + 31522219 = 31522376
397 + 31521979 = 31522376
547 + 31521829 = 31522376

Showing the first eight; more decompositions exist.
