Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187972, here are decompositions:

41 + 187931 = 187972
89 + 187883 = 187972
101 + 187871 = 187972
149 + 187823 = 187972
179 + 187793 = 187972
251 + 187721 = 187972
311 + 187661 = 187972
503 + 187469 = 187972

Showing the first eight; more decompositions exist.
