Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72860, here are decompositions:

37 + 72823 = 72860
43 + 72817 = 72860
97 + 72763 = 72860
127 + 72733 = 72860
181 + 72679 = 72860
199 + 72661 = 72860
211 + 72649 = 72860
283 + 72577 = 72860

Showing the first eight; more decompositions exist.
