Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49640, here are decompositions:

7 + 49633 = 49640
13 + 49627 = 49640
37 + 49603 = 49640
43 + 49597 = 49640
103 + 49537 = 49640
109 + 49531 = 49640
163 + 49477 = 49640
181 + 49459 = 49640

Showing the first eight; more decompositions exist.
