Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623314, here are decompositions:

103 + 31623211 = 31623314
193 + 31623121 = 31623314
367 + 31622947 = 31623314
421 + 31622893 = 31623314
433 + 31622881 = 31623314
571 + 31622743 = 31623314
601 + 31622713 = 31623314
631 + 31622683 = 31623314

Showing the first eight; more decompositions exist.
