Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123904, here are decompositions:

17 + 123887 = 123904
41 + 123863 = 123904
71 + 123833 = 123904
83 + 123821 = 123904
101 + 123803 = 123904
113 + 123791 = 123904
167 + 123737 = 123904
173 + 123731 = 123904

Showing the first eight; more decompositions exist.
