Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731286, here are decompositions:

37 + 8731249 = 8731286
73 + 8731213 = 8731286
337 + 8730949 = 8731286
367 + 8730919 = 8731286
373 + 8730913 = 8731286
397 + 8730889 = 8731286
439 + 8730847 = 8731286
709 + 8730577 = 8731286

Showing the first eight; more decompositions exist.
