Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625780, here are decompositions:

47 + 8625733 = 8625780
71 + 8625709 = 8625780
73 + 8625707 = 8625780
131 + 8625649 = 8625780
139 + 8625641 = 8625780
181 + 8625599 = 8625780
193 + 8625587 = 8625780
227 + 8625553 = 8625780

Showing the first eight; more decompositions exist.
