Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629138, here are decompositions:

29 + 8629109 = 8629138
59 + 8629079 = 8629138
239 + 8628899 = 8629138
281 + 8628857 = 8629138
347 + 8628791 = 8629138
359 + 8628779 = 8629138
461 + 8628677 = 8629138
491 + 8628647 = 8629138

Showing the first eight; more decompositions exist.
