Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747772, here are decompositions:

13 + 8747759 = 8747772
29 + 8747743 = 8747772
71 + 8747701 = 8747772
83 + 8747689 = 8747772
149 + 8747623 = 8747772
193 + 8747579 = 8747772
199 + 8747573 = 8747772
211 + 8747561 = 8747772

Showing the first eight; more decompositions exist.
