Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 60640, here are decompositions:

3 + 60637 = 60640
17 + 60623 = 60640
23 + 60617 = 60640
29 + 60611 = 60640
101 + 60539 = 60640
113 + 60527 = 60640
131 + 60509 = 60640
191 + 60449 = 60640

Showing the first eight; more decompositions exist.
