Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987842, here are decompositions:

43 + 4294987799 = 4294987842
71 + 4294987771 = 4294987842
73 + 4294987769 = 4294987842
139 + 4294987703 = 4294987842
191 + 4294987651 = 4294987842
263 + 4294987579 = 4294987842
281 + 4294987561 = 4294987842
449 + 4294987393 = 4294987842

Showing the first eight; more decompositions exist.
