Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619470, here are decompositions:

31 + 8619439 = 8619470
37 + 8619433 = 8619470
43 + 8619427 = 8619470
73 + 8619397 = 8619470
127 + 8619343 = 8619470
229 + 8619241 = 8619470
241 + 8619229 = 8619470
271 + 8619199 = 8619470

Showing the first eight; more decompositions exist.
