Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610940, here are decompositions:

3 + 8610937 = 8610940
47 + 8610893 = 8610940
59 + 8610881 = 8610940
89 + 8610851 = 8610940
113 + 8610827 = 8610940
137 + 8610803 = 8610940
281 + 8610659 = 8610940
383 + 8610557 = 8610940

Showing the first eight; more decompositions exist.
