Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47042, here are decompositions:

109 + 46933 = 47042
181 + 46861 = 47042
211 + 46831 = 47042
223 + 46819 = 47042
271 + 46771 = 47042
379 + 46663 = 47042
409 + 46633 = 47042
571 + 46471 = 47042

Showing the first eight; more decompositions exist.
