Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76620, here are decompositions:

13 + 76607 = 76620
17 + 76603 = 76620
23 + 76597 = 76620
41 + 76579 = 76620
59 + 76561 = 76620
79 + 76541 = 76620
83 + 76537 = 76620
101 + 76519 = 76620

Showing the first eight; more decompositions exist.
