Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484292, here are decompositions:

11 + 31484281 = 31484292
53 + 31484239 = 31484292
83 + 31484209 = 31484292
89 + 31484203 = 31484292
113 + 31484179 = 31484292
131 + 31484161 = 31484292
149 + 31484143 = 31484292
163 + 31484129 = 31484292

Showing the first eight; more decompositions exist.
