Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678434, here are decompositions:

41 + 8678393 = 8678434
71 + 8678363 = 8678434
101 + 8678333 = 8678434
197 + 8678237 = 8678434
293 + 8678141 = 8678434
353 + 8678081 = 8678434
383 + 8678051 = 8678434
467 + 8677967 = 8678434

Showing the first eight; more decompositions exist.
