Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137478, here are decompositions:

31 + 137447 = 137478
41 + 137437 = 137478
79 + 137399 = 137478
109 + 137369 = 137478
137 + 137341 = 137478
139 + 137339 = 137478
157 + 137321 = 137478
199 + 137279 = 137478

Showing the first eight; more decompositions exist.
