Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37658, here are decompositions:

67 + 37591 = 37658
79 + 37579 = 37658
97 + 37561 = 37658
109 + 37549 = 37658
151 + 37507 = 37658
157 + 37501 = 37658
211 + 37447 = 37658
337 + 37321 = 37658

Showing the first eight; more decompositions exist.
