Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629240, here are decompositions:

41 + 8629199 = 8629240
47 + 8629193 = 8629240
71 + 8629169 = 8629240
83 + 8629157 = 8629240
101 + 8629139 = 8629240
131 + 8629109 = 8629240
167 + 8629073 = 8629240
317 + 8628923 = 8629240

Showing the first eight; more decompositions exist.
