Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625980, here are decompositions:

7 + 8625973 = 8625980
19 + 8625961 = 8625980
67 + 8625913 = 8625980
79 + 8625901 = 8625980
127 + 8625853 = 8625980
193 + 8625787 = 8625980
271 + 8625709 = 8625980
331 + 8625649 = 8625980

Showing the first eight; more decompositions exist.
