Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123802, here are decompositions:

11 + 123791 = 123802
71 + 123731 = 123802
83 + 123719 = 123802
101 + 123701 = 123802
149 + 123653 = 123802
251 + 123551 = 123802
311 + 123491 = 123802
353 + 123449 = 123802

Showing the first eight; more decompositions exist.
