Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987378, here are decompositions:

47 + 4294987331 = 4294987378
89 + 4294987289 = 4294987378
317 + 4294987061 = 4294987378
389 + 4294986989 = 4294987378
419 + 4294986959 = 4294987378
467 + 4294986911 = 4294987378
641 + 4294986737 = 4294987378
677 + 4294986701 = 4294987378

Showing the first eight; more decompositions exist.
