Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629378, here are decompositions:

29 + 8629349 = 8629378
137 + 8629241 = 8629378
179 + 8629199 = 8629378
239 + 8629139 = 8629378
269 + 8629109 = 8629378
479 + 8628899 = 8629378
521 + 8628857 = 8629378
587 + 8628791 = 8629378

Showing the first eight; more decompositions exist.
