Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77550, here are decompositions:

7 + 77543 = 77550
23 + 77527 = 77550
29 + 77521 = 77550
37 + 77513 = 77550
41 + 77509 = 77550
59 + 77491 = 77550
61 + 77489 = 77550
71 + 77479 = 77550

Showing the first eight; more decompositions exist.
