Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988390, here are decompositions:

3 + 4294988387 = 4294988390
13 + 4294988377 = 4294988390
37 + 4294988353 = 4294988390
79 + 4294988311 = 4294988390
157 + 4294988233 = 4294988390
163 + 4294988227 = 4294988390
193 + 4294988197 = 4294988390
211 + 4294988179 = 4294988390

Showing the first eight; more decompositions exist.
