Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990578, here are decompositions:

17 + 4294990561 = 4294990578
101 + 4294990477 = 4294990578
149 + 4294990429 = 4294990578
227 + 4294990351 = 4294990578
257 + 4294990321 = 4294990578
331 + 4294990247 = 4294990578
337 + 4294990241 = 4294990578
449 + 4294990129 = 4294990578

Showing the first eight; more decompositions exist.
