Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629372, here are decompositions:

23 + 8629349 = 8629372
29 + 8629343 = 8629372
131 + 8629241 = 8629372
173 + 8629199 = 8629372
179 + 8629193 = 8629372
233 + 8629139 = 8629372
263 + 8629109 = 8629372
293 + 8629079 = 8629372

Showing the first eight; more decompositions exist.
