Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761772, here are decompositions:

139 + 8761633 = 8761772
241 + 8761531 = 8761772
433 + 8761339 = 8761772
619 + 8761153 = 8761772
631 + 8761141 = 8761772
673 + 8761099 = 8761772
991 + 8760781 = 8761772
1051 + 8760721 = 8761772

Showing the first eight; more decompositions exist.
