Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738158, here are decompositions:

29 + 8738129 = 8738158
71 + 8738087 = 8738158
179 + 8737979 = 8738158
449 + 8737709 = 8738158
461 + 8737697 = 8738158
491 + 8737667 = 8738158
587 + 8737571 = 8738158
677 + 8737481 = 8738158

Showing the first eight; more decompositions exist.
