Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662390, here are decompositions:

41 + 8662349 = 8662390
47 + 8662343 = 8662390
53 + 8662337 = 8662390
71 + 8662319 = 8662390
131 + 8662259 = 8662390
167 + 8662223 = 8662390
173 + 8662217 = 8662390
239 + 8662151 = 8662390

Showing the first eight; more decompositions exist.
