Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957390, here are decompositions:

41 + 4294957349 = 4294957390
71 + 4294957319 = 4294957390
83 + 4294957307 = 4294957390
233 + 4294957157 = 4294957390
281 + 4294957109 = 4294957390
401 + 4294956989 = 4294957390
467 + 4294956923 = 4294957390
509 + 4294956881 = 4294957390

Showing the first eight; more decompositions exist.
