Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011542, here are decompositions:

3 + 1011539 = 1011542
151 + 1011391 = 1011542
193 + 1011349 = 1011542
199 + 1011343 = 1011542
211 + 1011331 = 1011542
271 + 1011271 = 1011542
313 + 1011229 = 1011542
379 + 1011163 = 1011542

Showing the first eight; more decompositions exist.
