Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137862, here are decompositions:

13 + 137849 = 137862
31 + 137831 = 137862
59 + 137803 = 137862
71 + 137791 = 137862
139 + 137723 = 137862
149 + 137713 = 137862
163 + 137699 = 137862
223 + 137639 = 137862

Showing the first eight; more decompositions exist.
