Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15040, here are decompositions:

23 + 15017 = 15040
71 + 14969 = 15040
83 + 14957 = 15040
89 + 14951 = 15040
101 + 14939 = 15040
149 + 14891 = 15040
173 + 14867 = 15040
197 + 14843 = 15040

Showing the first eight; more decompositions exist.
