Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991648, here are decompositions:

61 + 4294991587 = 4294991648
97 + 4294991551 = 4294991648
109 + 4294991539 = 4294991648
127 + 4294991521 = 4294991648
139 + 4294991509 = 4294991648
151 + 4294991497 = 4294991648
397 + 4294991251 = 4294991648
487 + 4294991161 = 4294991648

Showing the first eight; more decompositions exist.
