Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137910, here are decompositions:

37 + 137873 = 137910
41 + 137869 = 137910
43 + 137867 = 137910
61 + 137849 = 137910
79 + 137831 = 137910
83 + 137827 = 137910
107 + 137803 = 137910
139 + 137771 = 137910

Showing the first eight; more decompositions exist.
