Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186012, here are decompositions:

5 + 186007 = 186012
19 + 185993 = 186012
41 + 185971 = 186012
53 + 185959 = 186012
61 + 185951 = 186012
89 + 185923 = 186012
109 + 185903 = 186012
139 + 185873 = 186012

Showing the first eight; more decompositions exist.
