Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180770, here are decompositions:

19 + 180751 = 180770
103 + 180667 = 180770
223 + 180547 = 180770
229 + 180541 = 180770
307 + 180463 = 180770
379 + 180391 = 180770
409 + 180361 = 180770
433 + 180337 = 180770

Showing the first eight; more decompositions exist.
