Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30040, here are decompositions:

11 + 30029 = 30040
29 + 30011 = 30040
113 + 29927 = 30040
167 + 29873 = 30040
173 + 29867 = 30040
251 + 29789 = 30040
281 + 29759 = 30040
317 + 29723 = 30040

Showing the first eight; more decompositions exist.
