Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597972, here are decompositions:

3 + 8597969 = 8597972
109 + 8597863 = 8597972
151 + 8597821 = 8597972
349 + 8597623 = 8597972
373 + 8597599 = 8597972
421 + 8597551 = 8597972
499 + 8597473 = 8597972
601 + 8597371 = 8597972

Showing the first eight; more decompositions exist.
