Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530292, here are decompositions:

23 + 31530269 = 31530292
89 + 31530203 = 31530292
149 + 31530143 = 31530292
263 + 31530029 = 31530292
359 + 31529933 = 31530292
401 + 31529891 = 31530292
449 + 31529843 = 31530292
509 + 31529783 = 31530292

Showing the first eight; more decompositions exist.
