Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187996, here are decompositions:

23 + 187973 = 187996
89 + 187907 = 187996
113 + 187883 = 187996
173 + 187823 = 187996
233 + 187763 = 187996
359 + 187637 = 187996
449 + 187547 = 187996
563 + 187433 = 187996

Showing the first eight; more decompositions exist.
