Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629540, here are decompositions:

107 + 8629433 = 8629540
131 + 8629409 = 8629540
191 + 8629349 = 8629540
197 + 8629343 = 8629540
347 + 8629193 = 8629540
383 + 8629157 = 8629540
401 + 8629139 = 8629540
431 + 8629109 = 8629540

Showing the first eight; more decompositions exist.
