Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991172, here are decompositions:

5 + 4294991167 = 4294991172
11 + 4294991161 = 4294991172
23 + 4294991149 = 4294991172
53 + 4294991119 = 4294991172
61 + 4294991111 = 4294991172
139 + 4294991033 = 4294991172
149 + 4294991023 = 4294991172
401 + 4294990771 = 4294991172

Showing the first eight; more decompositions exist.
