Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671172, here are decompositions:

73 + 8671099 = 8671172
109 + 8671063 = 8671172
163 + 8671009 = 8671172
229 + 8670943 = 8671172
421 + 8670751 = 8671172
463 + 8670709 = 8671172
613 + 8670559 = 8671172
619 + 8670553 = 8671172

Showing the first eight; more decompositions exist.
