Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137312, here are decompositions:

61 + 137251 = 137312
73 + 137239 = 137312
103 + 137209 = 137312
181 + 137131 = 137312
193 + 137119 = 137312
223 + 137089 = 137312
283 + 137029 = 137312
313 + 136999 = 137312

Showing the first eight; more decompositions exist.
