Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719472, here are decompositions:

31 + 8719441 = 8719472
199 + 8719273 = 8719472
211 + 8719261 = 8719472
313 + 8719159 = 8719472
331 + 8719141 = 8719472
373 + 8719099 = 8719472
499 + 8718973 = 8719472
523 + 8718949 = 8719472

Showing the first eight; more decompositions exist.
