Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522468, here are decompositions:

17 + 31522451 = 31522468
137 + 31522331 = 31522468
191 + 31522277 = 31522468
227 + 31522241 = 31522468
239 + 31522229 = 31522468
449 + 31522019 = 31522468
491 + 31521977 = 31522468
617 + 31521851 = 31522468

Showing the first eight; more decompositions exist.
