Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538442, here are decompositions:

19 + 538423 = 538442
31 + 538411 = 538442
43 + 538399 = 538442
109 + 538333 = 538442
139 + 538303 = 538442
193 + 538249 = 538442
241 + 538201 = 538442
283 + 538159 = 538442

Showing the first eight; more decompositions exist.
