Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670972, here are decompositions:

29 + 8670943 = 8670972
31 + 8670941 = 8670972
53 + 8670919 = 8670972
103 + 8670869 = 8670972
109 + 8670863 = 8670972
181 + 8670791 = 8670972
199 + 8670773 = 8670972
229 + 8670743 = 8670972

Showing the first eight; more decompositions exist.
