Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137892, here are decompositions:

19 + 137873 = 137892
23 + 137869 = 137892
43 + 137849 = 137892
61 + 137831 = 137892
89 + 137803 = 137892
101 + 137791 = 137892
149 + 137743 = 137892
179 + 137713 = 137892

Showing the first eight; more decompositions exist.
