Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629142, here are decompositions:

3 + 8629139 = 8629142
19 + 8629123 = 8629142
79 + 8629063 = 8629142
139 + 8629003 = 8629142
229 + 8628913 = 8629142
283 + 8628859 = 8629142
331 + 8628811 = 8629142
433 + 8628709 = 8629142

Showing the first eight; more decompositions exist.
