Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048942, here are decompositions:

23 + 1048919 = 1048942
53 + 1048889 = 1048942
113 + 1048829 = 1048942
149 + 1048793 = 1048942
233 + 1048709 = 1048942
239 + 1048703 = 1048942
281 + 1048661 = 1048942
353 + 1048589 = 1048942

Showing the first eight; more decompositions exist.
