Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623290, here are decompositions:

29 + 8623261 = 8623290
37 + 8623253 = 8623290
41 + 8623249 = 8623290
43 + 8623247 = 8623290
97 + 8623193 = 8623290
149 + 8623141 = 8623290
167 + 8623123 = 8623290
223 + 8623067 = 8623290

Showing the first eight; more decompositions exist.
