Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657390, here are decompositions:

3 + 8657387 = 8657390
13 + 8657377 = 8657390
67 + 8657323 = 8657390
151 + 8657239 = 8657390
229 + 8657161 = 8657390
337 + 8657053 = 8657390
349 + 8657041 = 8657390
373 + 8657017 = 8657390

Showing the first eight; more decompositions exist.
