Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748772, here are decompositions:

5 + 8748767 = 8748772
29 + 8748743 = 8748772
41 + 8748731 = 8748772
59 + 8748713 = 8748772
173 + 8748599 = 8748772
191 + 8748581 = 8748772
269 + 8748503 = 8748772
353 + 8748419 = 8748772

Showing the first eight; more decompositions exist.
