Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678402, here are decompositions:

3 + 8678399 = 8678402
43 + 8678359 = 8678402
79 + 8678323 = 8678402
199 + 8678203 = 8678402
223 + 8678179 = 8678402
241 + 8678161 = 8678402
349 + 8678053 = 8678402
373 + 8678029 = 8678402

Showing the first eight; more decompositions exist.
