Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628424, here are decompositions:

3 + 8628421 = 8628424
17 + 8628407 = 8628424
41 + 8628383 = 8628424
47 + 8628377 = 8628424
71 + 8628353 = 8628424
131 + 8628293 = 8628424
191 + 8628233 = 8628424
251 + 8628173 = 8628424

Showing the first eight; more decompositions exist.
