Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021800, here are decompositions:

101 + 4295021699 = 4295021800
137 + 4295021663 = 4295021800
191 + 4295021609 = 4295021800
233 + 4295021567 = 4295021800
317 + 4295021483 = 4295021800
347 + 4295021453 = 4295021800
521 + 4295021279 = 4295021800
593 + 4295021207 = 4295021800

Showing the first eight; more decompositions exist.
