Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662972, here are decompositions:

29 + 8662943 = 8662972
83 + 8662889 = 8662972
113 + 8662859 = 8662972
173 + 8662799 = 8662972
389 + 8662583 = 8662972
419 + 8662553 = 8662972
431 + 8662541 = 8662972
491 + 8662481 = 8662972

Showing the first eight; more decompositions exist.
