Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618330, here are decompositions:

3 + 8618327 = 8618330
13 + 8618317 = 8618330
37 + 8618293 = 8618330
43 + 8618287 = 8618330
73 + 8618257 = 8618330
79 + 8618251 = 8618330
109 + 8618221 = 8618330
157 + 8618173 = 8618330

Showing the first eight; more decompositions exist.
