Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991180, here are decompositions:

13 + 4294991167 = 4294991180
19 + 4294991161 = 4294991180
31 + 4294991149 = 4294991180
61 + 4294991119 = 4294991180
127 + 4294991053 = 4294991180
157 + 4294991023 = 4294991180
409 + 4294990771 = 4294991180
457 + 4294990723 = 4294991180

Showing the first eight; more decompositions exist.
