Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629580, here are decompositions:

19 + 8629561 = 8629580
73 + 8629507 = 8629580
97 + 8629483 = 8629580
139 + 8629441 = 8629580
151 + 8629429 = 8629580
283 + 8629297 = 8629580
367 + 8629213 = 8629580
409 + 8629171 = 8629580

Showing the first eight; more decompositions exist.
