Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709772, here are decompositions:

41 + 8709731 = 8709772
53 + 8709719 = 8709772
59 + 8709713 = 8709772
263 + 8709509 = 8709772
311 + 8709461 = 8709772
389 + 8709383 = 8709772
809 + 8708963 = 8709772
941 + 8708831 = 8709772

Showing the first eight; more decompositions exist.
