Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37648, here are decompositions:

5 + 37643 = 37648
29 + 37619 = 37648
41 + 37607 = 37648
59 + 37589 = 37648
101 + 37547 = 37648
131 + 37517 = 37648
137 + 37511 = 37648
239 + 37409 = 37648

Showing the first eight; more decompositions exist.
