Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716490, here are decompositions:

37 + 8716453 = 8716490
43 + 8716447 = 8716490
61 + 8716429 = 8716490
109 + 8716381 = 8716490
241 + 8716249 = 8716490
271 + 8716219 = 8716490
283 + 8716207 = 8716490
331 + 8716159 = 8716490

Showing the first eight; more decompositions exist.
