Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623190, here are decompositions:

17 + 31623173 = 31623190
23 + 31623167 = 31623190
149 + 31623041 = 31623190
167 + 31623023 = 31623190
239 + 31622951 = 31623190
251 + 31622939 = 31623190
257 + 31622933 = 31623190
353 + 31622837 = 31623190

Showing the first eight; more decompositions exist.
