Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485292, here are decompositions:

23 + 31485269 = 31485292
71 + 31485221 = 31485292
101 + 31485191 = 31485292
191 + 31485101 = 31485292
233 + 31485059 = 31485292
269 + 31485023 = 31485292
389 + 31484903 = 31485292
491 + 31484801 = 31485292

Showing the first eight; more decompositions exist.
