Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000542, here are decompositions:

5 + 1000537 = 1000542
89 + 1000453 = 1000542
113 + 1000429 = 1000542
139 + 1000403 = 1000542
149 + 1000393 = 1000542
229 + 1000313 = 1000542
239 + 1000303 = 1000542
251 + 1000291 = 1000542

Showing the first eight; more decompositions exist.
