Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623292, here are decompositions:

83 + 31623209 = 31623292
179 + 31623113 = 31623292
251 + 31623041 = 31623292
269 + 31623023 = 31623292
353 + 31622939 = 31623292
359 + 31622933 = 31623292
563 + 31622729 = 31623292
593 + 31622699 = 31623292

Showing the first eight; more decompositions exist.
