Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678408, here are decompositions:

97 + 8678311 = 8678408
229 + 8678179 = 8678408
379 + 8678029 = 8678408
397 + 8678011 = 8678408
457 + 8677951 = 8678408
727 + 8677681 = 8678408
757 + 8677651 = 8678408
1009 + 8677399 = 8678408

Showing the first eight; more decompositions exist.
