Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77042, here are decompositions:

13 + 77029 = 77042
19 + 77023 = 77042
79 + 76963 = 77042
211 + 76831 = 77042
223 + 76819 = 77042
241 + 76801 = 77042
271 + 76771 = 77042
439 + 76603 = 77042

Showing the first eight; more decompositions exist.
