Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048542, here are decompositions:

109 + 1048433 = 1048542
151 + 1048391 = 1048542
181 + 1048361 = 1048542
199 + 1048343 = 1048542
233 + 1048309 = 1048542
251 + 1048291 = 1048542
269 + 1048273 = 1048542
281 + 1048261 = 1048542

Showing the first eight; more decompositions exist.
