Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987680, here are decompositions:

29 + 4294987651 = 4294987680
59 + 4294987621 = 4294987680
73 + 4294987607 = 4294987680
101 + 4294987579 = 4294987680
157 + 4294987523 = 4294987680
293 + 4294987387 = 4294987680
349 + 4294987331 = 4294987680
449 + 4294987231 = 4294987680

Showing the first eight; more decompositions exist.
