Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678428, here are decompositions:

29 + 8678399 = 8678428
89 + 8678339 = 8678428
191 + 8678237 = 8678428
281 + 8678147 = 8678428
347 + 8678081 = 8678428
359 + 8678069 = 8678428
389 + 8678039 = 8678428
401 + 8678027 = 8678428

Showing the first eight; more decompositions exist.
