Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657772, here are decompositions:

5 + 8657767 = 8657772
41 + 8657731 = 8657772
73 + 8657699 = 8657772
139 + 8657633 = 8657772
239 + 8657533 = 8657772
269 + 8657503 = 8657772
311 + 8657461 = 8657772
349 + 8657423 = 8657772

Showing the first eight; more decompositions exist.
