Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729370, here are decompositions:

37 + 8729333 = 8729370
43 + 8729327 = 8729370
47 + 8729323 = 8729370
53 + 8729317 = 8729370
61 + 8729309 = 8729370
79 + 8729291 = 8729370
127 + 8729243 = 8729370
131 + 8729239 = 8729370

Showing the first eight; more decompositions exist.
