Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957840, here are decompositions:

59 + 4294957781 = 4294957840
137 + 4294957703 = 4294957840
197 + 4294957643 = 4294957840
317 + 4294957523 = 4294957840
347 + 4294957493 = 4294957840
401 + 4294957439 = 4294957840
443 + 4294957397 = 4294957840
491 + 4294957349 = 4294957840

Showing the first eight; more decompositions exist.
