Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37640, here are decompositions:

7 + 37633 = 37640
61 + 37579 = 37640
67 + 37573 = 37640
73 + 37567 = 37640
79 + 37561 = 37640
103 + 37537 = 37640
139 + 37501 = 37640
151 + 37489 = 37640

Showing the first eight; more decompositions exist.
