Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699972, here are decompositions:

3 + 8699969 = 8699972
13 + 8699959 = 8699972
19 + 8699953 = 8699972
79 + 8699893 = 8699972
241 + 8699731 = 8699972
313 + 8699659 = 8699972
331 + 8699641 = 8699972
433 + 8699539 = 8699972

Showing the first eight; more decompositions exist.
