Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973638, here are decompositions:

5 + 4294973633 = 4294973638
89 + 4294973549 = 4294973638
101 + 4294973537 = 4294973638
107 + 4294973531 = 4294973638
251 + 4294973387 = 4294973638
317 + 4294973321 = 4294973638
491 + 4294973147 = 4294973638
521 + 4294973117 = 4294973638

Showing the first eight; more decompositions exist.
