Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492838, here are decompositions:

107 + 492731 = 492838
131 + 492707 = 492838
167 + 492671 = 492838
179 + 492659 = 492838
191 + 492647 = 492838
197 + 492641 = 492838
251 + 492587 = 492838
347 + 492491 = 492838

Showing the first eight; more decompositions exist.
