Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37512, here are decompositions:

5 + 37507 = 37512
11 + 37501 = 37512
19 + 37493 = 37512
23 + 37489 = 37512
29 + 37483 = 37512
71 + 37441 = 37512
89 + 37423 = 37512
103 + 37409 = 37512

Showing the first eight; more decompositions exist.
