Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630780, here are decompositions:

31 + 8630749 = 8630780
43 + 8630737 = 8630780
97 + 8630683 = 8630780
127 + 8630653 = 8630780
139 + 8630641 = 8630780
181 + 8630599 = 8630780
331 + 8630449 = 8630780
337 + 8630443 = 8630780

Showing the first eight; more decompositions exist.
