Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985478, here are decompositions:

11 + 4294985467 = 4294985478
19 + 4294985459 = 4294985478
29 + 4294985449 = 4294985478
41 + 4294985437 = 4294985478
79 + 4294985399 = 4294985478
101 + 4294985377 = 4294985478
167 + 4294985311 = 4294985478
191 + 4294985287 = 4294985478

Showing the first eight; more decompositions exist.
