Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985878, here are decompositions:

41 + 4294985837 = 4294985878
137 + 4294985741 = 4294985878
347 + 4294985531 = 4294985878
419 + 4294985459 = 4294985878
479 + 4294985399 = 4294985878
569 + 4294985309 = 4294985878
587 + 4294985291 = 4294985878
641 + 4294985237 = 4294985878

Showing the first eight; more decompositions exist.
