Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186072, here are decompositions:

23 + 186049 = 186072
31 + 186041 = 186072
53 + 186019 = 186072
59 + 186013 = 186072
79 + 185993 = 186072
101 + 185971 = 186072
113 + 185959 = 186072
149 + 185923 = 186072

Showing the first eight; more decompositions exist.
