Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623370, here are decompositions:

113 + 31623257 = 31623370
197 + 31623173 = 31623370
257 + 31623113 = 31623370
347 + 31623023 = 31623370
419 + 31622951 = 31623370
431 + 31622939 = 31623370
593 + 31622777 = 31623370
641 + 31622729 = 31623370

Showing the first eight; more decompositions exist.
