Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957438, here are decompositions:

41 + 4294957397 = 4294957438
89 + 4294957349 = 4294957438
131 + 4294957307 = 4294957438
281 + 4294957157 = 4294957438
449 + 4294956989 = 4294957438
557 + 4294956881 = 4294957438
599 + 4294956839 = 4294957438
719 + 4294956719 = 4294957438

Showing the first eight; more decompositions exist.
