Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016542, here are decompositions:

53 + 1016489 = 1016542
89 + 1016453 = 1016542
101 + 1016441 = 1016542
239 + 1016303 = 1016542
311 + 1016231 = 1016542
383 + 1016159 = 1016542
389 + 1016153 = 1016542
419 + 1016123 = 1016542

Showing the first eight; more decompositions exist.
