Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167390, here are decompositions:

61 + 167329 = 167390
73 + 167317 = 167390
79 + 167311 = 167390
193 + 167197 = 167390
199 + 167191 = 167390
241 + 167149 = 167390
271 + 167119 = 167390
277 + 167113 = 167390

Showing the first eight; more decompositions exist.
