Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072730, here are decompositions:

17 + 4295072713 = 4295072730
41 + 4295072689 = 4295072730
61 + 4295072669 = 4295072730
211 + 4295072519 = 4295072730
241 + 4295072489 = 4295072730
293 + 4295072437 = 4295072730
367 + 4295072363 = 4295072730
461 + 4295072269 = 4295072730

Showing the first eight; more decompositions exist.
