Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188520, here are decompositions:

29 + 188491 = 188520
37 + 188483 = 188520
47 + 188473 = 188520
61 + 188459 = 188520
83 + 188437 = 188520
89 + 188431 = 188520
103 + 188417 = 188520
113 + 188407 = 188520

Showing the first eight; more decompositions exist.
