Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178126, here are decompositions:

23 + 178103 = 178126
59 + 178067 = 178126
89 + 178037 = 178126
173 + 177953 = 178126
197 + 177929 = 178126
233 + 177893 = 178126
239 + 177887 = 178126
383 + 177743 = 178126

Showing the first eight; more decompositions exist.
