Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137168, here are decompositions:

37 + 137131 = 137168
79 + 137089 = 137168
139 + 137029 = 137168
181 + 136987 = 137168
271 + 136897 = 137168
307 + 136861 = 137168
457 + 136711 = 137168
547 + 136621 = 137168

Showing the first eight; more decompositions exist.
