Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672132, here are decompositions:

31 + 8672101 = 8672132
151 + 8671981 = 8672132
421 + 8671711 = 8672132
463 + 8671669 = 8672132
499 + 8671633 = 8672132
613 + 8671519 = 8672132
631 + 8671501 = 8672132
661 + 8671471 = 8672132

Showing the first eight; more decompositions exist.
