Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670742, here are decompositions:

29 + 8670713 = 8670742
89 + 8670653 = 8670742
131 + 8670611 = 8670742
191 + 8670551 = 8670742
233 + 8670509 = 8670742
239 + 8670503 = 8670742
251 + 8670491 = 8670742
389 + 8670353 = 8670742

Showing the first eight; more decompositions exist.
