Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188450, here are decompositions:

7 + 188443 = 188450
13 + 188437 = 188450
19 + 188431 = 188450
43 + 188407 = 188450
61 + 188389 = 188450
127 + 188323 = 188450
139 + 188311 = 188450
151 + 188299 = 188450

Showing the first eight; more decompositions exist.
