Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987972, here are decompositions:

53 + 4294987919 = 4294987972
83 + 4294987889 = 4294987972
113 + 4294987859 = 4294987972
173 + 4294987799 = 4294987972
269 + 4294987703 = 4294987972
383 + 4294987589 = 4294987972
449 + 4294987523 = 4294987972
641 + 4294987331 = 4294987972

Showing the first eight; more decompositions exist.
