Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623112, here are decompositions:

71 + 31623041 = 31623112
89 + 31623023 = 31623112
173 + 31622939 = 31623112
179 + 31622933 = 31623112
383 + 31622729 = 31623112
419 + 31622693 = 31623112
449 + 31622663 = 31623112
593 + 31622519 = 31623112

Showing the first eight; more decompositions exist.
