Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987420, here are decompositions:

89 + 4294987331 = 4294987420
131 + 4294987289 = 4294987420
263 + 4294987157 = 4294987420
359 + 4294987061 = 4294987420
431 + 4294986989 = 4294987420
461 + 4294986959 = 4294987420
467 + 4294986953 = 4294987420
509 + 4294986911 = 4294987420

Showing the first eight; more decompositions exist.
