Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623206, here are decompositions:

7 + 31623199 = 31623206
37 + 31623169 = 31623206
283 + 31622923 = 31623206
313 + 31622893 = 31623206
397 + 31622809 = 31623206
463 + 31622743 = 31623206
523 + 31622683 = 31623206
577 + 31622629 = 31623206

Showing the first eight; more decompositions exist.
