Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971940, here are decompositions:

3 + 4294971937 = 4294971940
11 + 4294971929 = 4294971940
383 + 4294971557 = 4294971940
443 + 4294971497 = 4294971940
449 + 4294971491 = 4294971940
509 + 4294971431 = 4294971940
563 + 4294971377 = 4294971940
617 + 4294971323 = 4294971940

Showing the first eight; more decompositions exist.
