Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187012, here are decompositions:

3 + 187009 = 187012
53 + 186959 = 187012
239 + 186773 = 187012
251 + 186761 = 187012
269 + 186743 = 187012
311 + 186701 = 187012
359 + 186653 = 187012
383 + 186629 = 187012

Showing the first eight; more decompositions exist.
