Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 372, here are decompositions:

5 + 367 = 372
13 + 359 = 372
19 + 353 = 372
23 + 349 = 372
41 + 331 = 372
59 + 313 = 372
61 + 311 = 372
79 + 293 = 372

Showing the first eight; more decompositions exist.
