Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986678, here are decompositions:

29 + 4294986649 = 4294986678
131 + 4294986547 = 4294986678
167 + 4294986511 = 4294986678
181 + 4294986497 = 4294986678
239 + 4294986439 = 4294986678
337 + 4294986341 = 4294986678
347 + 4294986331 = 4294986678
401 + 4294986277 = 4294986678

Showing the first eight; more decompositions exist.
