Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987578, here are decompositions:

17 + 4294987561 = 4294987578
151 + 4294987427 = 4294987578
191 + 4294987387 = 4294987578
347 + 4294987231 = 4294987578
421 + 4294987157 = 4294987578
467 + 4294987111 = 4294987578
521 + 4294987057 = 4294987578
587 + 4294986991 = 4294987578

Showing the first eight; more decompositions exist.
