Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618740, here are decompositions:

3 + 8618737 = 8618740
41 + 8618699 = 8618740
59 + 8618681 = 8618740
101 + 8618639 = 8618740
149 + 8618591 = 8618740
173 + 8618567 = 8618740
239 + 8618501 = 8618740
257 + 8618483 = 8618740

Showing the first eight; more decompositions exist.
