Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972642, here are decompositions:

29 + 4294972613 = 4294972642
83 + 4294972559 = 4294972642
491 + 4294972151 = 4294972642
563 + 4294972079 = 4294972642
593 + 4294972049 = 4294972642
1151 + 4294971491 = 4294972642
1319 + 4294971323 = 4294972642
1373 + 4294971269 = 4294972642

Showing the first eight; more decompositions exist.
