Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188750, here are decompositions:

31 + 188719 = 188750
43 + 188707 = 188750
73 + 188677 = 188750
97 + 188653 = 188750
223 + 188527 = 188750
277 + 188473 = 188750
307 + 188443 = 188750
313 + 188437 = 188750

Showing the first eight; more decompositions exist.
