Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11042, here are decompositions:

103 + 10939 = 11042
139 + 10903 = 11042
151 + 10891 = 11042
181 + 10861 = 11042
211 + 10831 = 11042
271 + 10771 = 11042
313 + 10729 = 11042
331 + 10711 = 11042

Showing the first eight; more decompositions exist.
