Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994538, here are decompositions:

37 + 994501 = 994538
67 + 994471 = 994538
199 + 994339 = 994538
229 + 994309 = 994538
241 + 994297 = 994538
397 + 994141 = 994538
487 + 994051 = 994538
499 + 994039 = 994538

Showing the first eight; more decompositions exist.
