Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78742, here are decompositions:

5 + 78737 = 78742
29 + 78713 = 78742
89 + 78653 = 78742
149 + 78593 = 78742
173 + 78569 = 78742
233 + 78509 = 78742
263 + 78479 = 78742
401 + 78341 = 78742

Showing the first eight; more decompositions exist.
