Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177420, here are decompositions:

11 + 177409 = 177420
37 + 177383 = 177420
41 + 177379 = 177420
73 + 177347 = 177420
83 + 177337 = 177420
97 + 177323 = 177420
101 + 177319 = 177420
137 + 177283 = 177420

Showing the first eight; more decompositions exist.
