Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522444, here are decompositions:

3 + 31522441 = 31522444
11 + 31522433 = 31522444
71 + 31522373 = 31522444
113 + 31522331 = 31522444
131 + 31522313 = 31522444
167 + 31522277 = 31522444
197 + 31522247 = 31522444
263 + 31522181 = 31522444

Showing the first eight; more decompositions exist.
