Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672042, here are decompositions:

61 + 8671981 = 8672042
331 + 8671711 = 8672042
373 + 8671669 = 8672042
409 + 8671633 = 8672042
523 + 8671519 = 8672042
541 + 8671501 = 8672042
571 + 8671471 = 8672042
601 + 8671441 = 8672042

Showing the first eight; more decompositions exist.
