Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167780, here are decompositions:

3 + 167777 = 167780
97 + 167683 = 167780
103 + 167677 = 167780
139 + 167641 = 167780
157 + 167623 = 167780
331 + 167449 = 167780
337 + 167443 = 167780
367 + 167413 = 167780

Showing the first eight; more decompositions exist.
