Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957642, here are decompositions:

89 + 4294957553 = 4294957642
149 + 4294957493 = 4294957642
293 + 4294957349 = 4294957642
653 + 4294956989 = 4294957642
719 + 4294956923 = 4294957642
761 + 4294956881 = 4294957642
809 + 4294956833 = 4294957642
953 + 4294956689 = 4294957642

Showing the first eight; more decompositions exist.
