Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123888, here are decompositions:

59 + 123829 = 123888
67 + 123821 = 123888
71 + 123817 = 123888
97 + 123791 = 123888
101 + 123787 = 123888
131 + 123757 = 123888
151 + 123737 = 123888
157 + 123731 = 123888

Showing the first eight; more decompositions exist.
