Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704780, here are decompositions:

3 + 8704777 = 8704780
23 + 8704757 = 8704780
59 + 8704721 = 8704780
89 + 8704691 = 8704780
167 + 8704613 = 8704780
173 + 8704607 = 8704780
179 + 8704601 = 8704780
191 + 8704589 = 8704780

Showing the first eight; more decompositions exist.
