Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623182, here are decompositions:

13 + 31623169 = 31623182
61 + 31623121 = 31623182
223 + 31622959 = 31623182
373 + 31622809 = 31623182
379 + 31622803 = 31623182
439 + 31622743 = 31623182
499 + 31622683 = 31623182
541 + 31622641 = 31623182

Showing the first eight; more decompositions exist.
