Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186974, here are decompositions:

97 + 186877 = 186974
103 + 186871 = 186974
181 + 186793 = 186974
211 + 186763 = 186974
241 + 186733 = 186974
373 + 186601 = 186974
523 + 186451 = 186974
577 + 186397 = 186974

Showing the first eight; more decompositions exist.
