Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729312, here are decompositions:

3 + 8729309 = 8729312
73 + 8729239 = 8729312
139 + 8729173 = 8729312
181 + 8729131 = 8729312
349 + 8728963 = 8729312
409 + 8728903 = 8729312
463 + 8728849 = 8729312
601 + 8728711 = 8729312

Showing the first eight; more decompositions exist.
