Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37442, here are decompositions:

19 + 37423 = 37442
73 + 37369 = 37442
79 + 37363 = 37442
103 + 37339 = 37442
199 + 37243 = 37442
241 + 37201 = 37442
271 + 37171 = 37442
283 + 37159 = 37442

Showing the first eight; more decompositions exist.
