Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619940, here are decompositions:

3 + 8619937 = 8619940
47 + 8619893 = 8619940
71 + 8619869 = 8619940
83 + 8619857 = 8619940
149 + 8619791 = 8619940
167 + 8619773 = 8619940
227 + 8619713 = 8619940
257 + 8619683 = 8619940

Showing the first eight; more decompositions exist.
