Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123912, here are decompositions:

59 + 123853 = 123912
79 + 123833 = 123912
83 + 123829 = 123912
109 + 123803 = 123912
179 + 123733 = 123912
181 + 123731 = 123912
193 + 123719 = 123912
211 + 123701 = 123912

Showing the first eight; more decompositions exist.
