Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186518, here are decompositions:

37 + 186481 = 186518
67 + 186451 = 186518
127 + 186391 = 186518
139 + 186379 = 186518
271 + 186247 = 186518
307 + 186211 = 186518
331 + 186187 = 186518
421 + 186097 = 186518

Showing the first eight; more decompositions exist.
