Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494228, here are decompositions:

37 + 494191 = 494228
61 + 494167 = 494228
127 + 494101 = 494228
151 + 494077 = 494228
199 + 494029 = 494228
331 + 493897 = 494228
421 + 493807 = 494228
499 + 493729 = 494228

Showing the first eight; more decompositions exist.
