Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123844, here are decompositions:

11 + 123833 = 123844
23 + 123821 = 123844
41 + 123803 = 123844
53 + 123791 = 123844
107 + 123737 = 123844
113 + 123731 = 123844
137 + 123707 = 123844
167 + 123677 = 123844

Showing the first eight; more decompositions exist.
