Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978628, here are decompositions:

37 + 4294978591 = 4294978628
139 + 4294978489 = 4294978628
229 + 4294978399 = 4294978628
379 + 4294978249 = 4294978628
397 + 4294978231 = 4294978628
541 + 4294978087 = 4294978628
547 + 4294978081 = 4294978628
571 + 4294978057 = 4294978628

Showing the first eight; more decompositions exist.
