Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30772, here are decompositions:

59 + 30713 = 30772
83 + 30689 = 30772
101 + 30671 = 30772
179 + 30593 = 30772
233 + 30539 = 30772
263 + 30509 = 30772
281 + 30491 = 30772
383 + 30389 = 30772

Showing the first eight; more decompositions exist.
