Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543324, here are decompositions:

23 + 31543301 = 31543324
101 + 31543223 = 31543324
107 + 31543217 = 31543324
191 + 31543133 = 31543324
257 + 31543067 = 31543324
353 + 31542971 = 31543324
383 + 31542941 = 31543324
443 + 31542881 = 31543324

Showing the first eight; more decompositions exist.
