Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76638, here are decompositions:

7 + 76631 = 76638
31 + 76607 = 76638
41 + 76597 = 76638
59 + 76579 = 76638
97 + 76541 = 76638
101 + 76537 = 76638
127 + 76511 = 76638
131 + 76507 = 76638

Showing the first eight; more decompositions exist.
