Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700658, here are decompositions:

59 + 8700599 = 8700658
137 + 8700521 = 8700658
191 + 8700467 = 8700658
227 + 8700431 = 8700658
251 + 8700407 = 8700658
257 + 8700401 = 8700658
359 + 8700299 = 8700658
401 + 8700257 = 8700658

Showing the first eight; more decompositions exist.
