Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37778, here are decompositions:

31 + 37747 = 37778
61 + 37717 = 37778
79 + 37699 = 37778
199 + 37579 = 37778
211 + 37567 = 37778
229 + 37549 = 37778
241 + 37537 = 37778
271 + 37507 = 37778

Showing the first eight; more decompositions exist.
