Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671970, here are decompositions:

3 + 8671967 = 8671970
331 + 8671639 = 8671970
337 + 8671633 = 8671970
397 + 8671573 = 8671970
421 + 8671549 = 8671970
499 + 8671471 = 8671970
523 + 8671447 = 8671970
577 + 8671393 = 8671970

Showing the first eight; more decompositions exist.
