Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488942, here are decompositions:

109 + 488833 = 488942
151 + 488791 = 488942
163 + 488779 = 488942
193 + 488749 = 488942
199 + 488743 = 488942
241 + 488701 = 488942
331 + 488611 = 488942
439 + 488503 = 488942

Showing the first eight; more decompositions exist.
