Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180782, here are decompositions:

3 + 180779 = 180782
31 + 180751 = 180782
103 + 180679 = 180782
241 + 180541 = 180782
271 + 180511 = 180782
421 + 180361 = 180782
523 + 180259 = 180782
541 + 180241 = 180782

Showing the first eight; more decompositions exist.
