Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37780, here are decompositions:

89 + 37691 = 37780
131 + 37649 = 37780
137 + 37643 = 37780
173 + 37607 = 37780
191 + 37589 = 37780
233 + 37547 = 37780
251 + 37529 = 37780
263 + 37517 = 37780

Showing the first eight; more decompositions exist.
