Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678508, here are decompositions:

61 + 8678447 = 8678508
109 + 8678399 = 8678508
149 + 8678359 = 8678508
197 + 8678311 = 8678508
271 + 8678237 = 8678508
347 + 8678161 = 8678508
359 + 8678149 = 8678508
367 + 8678141 = 8678508

Showing the first eight; more decompositions exist.
