Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17780, here are decompositions:

19 + 17761 = 17780
31 + 17749 = 17780
43 + 17737 = 17780
67 + 17713 = 17780
73 + 17707 = 17780
97 + 17683 = 17780
157 + 17623 = 17780
181 + 17599 = 17780

Showing the first eight; more decompositions exist.
