Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654438, here are decompositions:

7 + 8654431 = 8654438
139 + 8654299 = 8654438
151 + 8654287 = 8654438
157 + 8654281 = 8654438
181 + 8654257 = 8654438
349 + 8654089 = 8654438
409 + 8654029 = 8654438
421 + 8654017 = 8654438

Showing the first eight; more decompositions exist.
