Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729992, here are decompositions:

53 + 8729939 = 8729992
191 + 8729801 = 8729992
263 + 8729729 = 8729992
281 + 8729711 = 8729992
311 + 8729681 = 8729992
389 + 8729603 = 8729992
449 + 8729543 = 8729992
563 + 8729429 = 8729992

Showing the first eight; more decompositions exist.
