Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543102, here are decompositions:

23 + 31543079 = 31543102
83 + 31543019 = 31543102
131 + 31542971 = 31543102
191 + 31542911 = 31543102
293 + 31542809 = 31543102
443 + 31542659 = 31543102
593 + 31542509 = 31543102
683 + 31542419 = 31543102

Showing the first eight; more decompositions exist.
