Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522488, here are decompositions:

29 + 31522459 = 31522488
37 + 31522451 = 31522488
47 + 31522441 = 31522488
131 + 31522357 = 31522488
149 + 31522339 = 31522488
157 + 31522331 = 31522488
191 + 31522297 = 31522488
211 + 31522277 = 31522488

Showing the first eight; more decompositions exist.
