Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188622, here are decompositions:

13 + 188609 = 188622
19 + 188603 = 188622
43 + 188579 = 188622
59 + 188563 = 188622
89 + 188533 = 188622
103 + 188519 = 188622
131 + 188491 = 188622
139 + 188483 = 188622

Showing the first eight; more decompositions exist.
