Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985778, here are decompositions:

37 + 4294985741 = 4294985778
131 + 4294985647 = 4294985778
197 + 4294985581 = 4294985778
311 + 4294985467 = 4294985778
379 + 4294985399 = 4294985778
401 + 4294985377 = 4294985778
467 + 4294985311 = 4294985778
487 + 4294985291 = 4294985778

Showing the first eight; more decompositions exist.
