Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678436, here are decompositions:

37 + 8678399 = 8678436
43 + 8678393 = 8678436
73 + 8678363 = 8678436
83 + 8678353 = 8678436
97 + 8678339 = 8678436
103 + 8678333 = 8678436
113 + 8678323 = 8678436
199 + 8678237 = 8678436

Showing the first eight; more decompositions exist.
