Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188722, here are decompositions:

3 + 188719 = 188722
11 + 188711 = 188722
29 + 188693 = 188722
41 + 188681 = 188722
89 + 188633 = 188722
101 + 188621 = 188722
113 + 188609 = 188722
239 + 188483 = 188722

Showing the first eight; more decompositions exist.
