Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177860, here are decompositions:

19 + 177841 = 177860
37 + 177823 = 177860
73 + 177787 = 177860
97 + 177763 = 177860
181 + 177679 = 177860
271 + 177589 = 177860
307 + 177553 = 177860
349 + 177511 = 177860

Showing the first eight; more decompositions exist.
