Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958420, here are decompositions:

19 + 4294958401 = 4294958420
139 + 4294958281 = 4294958420
163 + 4294958257 = 4294958420
223 + 4294958197 = 4294958420
349 + 4294958071 = 4294958420
409 + 4294958011 = 4294958420
463 + 4294957957 = 4294958420
691 + 4294957729 = 4294958420

Showing the first eight; more decompositions exist.
