Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699072, here are decompositions:

3 + 8699069 = 8699072
103 + 8698969 = 8699072
139 + 8698933 = 8699072
211 + 8698861 = 8699072
241 + 8698831 = 8699072
271 + 8698801 = 8699072
373 + 8698699 = 8699072
433 + 8698639 = 8699072

Showing the first eight; more decompositions exist.
