Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629144, here are decompositions:

3 + 8629141 = 8629144
5 + 8629139 = 8629144
71 + 8629073 = 8629144
353 + 8628791 = 8629144
467 + 8628677 = 8629144
521 + 8628623 = 8629144
593 + 8628551 = 8629144
701 + 8628443 = 8629144

Showing the first eight; more decompositions exist.
