Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719772, here are decompositions:

73 + 8719699 = 8719772
109 + 8719663 = 8719772
181 + 8719591 = 8719772
199 + 8719573 = 8719772
223 + 8719549 = 8719772
331 + 8719441 = 8719772
499 + 8719273 = 8719772
613 + 8719159 = 8719772

Showing the first eight; more decompositions exist.
