Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625890, here are decompositions:

37 + 8625853 = 8625890
79 + 8625811 = 8625890
103 + 8625787 = 8625890
157 + 8625733 = 8625890
181 + 8625709 = 8625890
241 + 8625649 = 8625890
331 + 8625559 = 8625890
337 + 8625553 = 8625890

Showing the first eight; more decompositions exist.
