Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623334, here are decompositions:

167 + 31623167 = 31623334
293 + 31623041 = 31623334
311 + 31623023 = 31623334
383 + 31622951 = 31623334
401 + 31622933 = 31623334
557 + 31622777 = 31623334
593 + 31622741 = 31623334
641 + 31622693 = 31623334

Showing the first eight; more decompositions exist.
