Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518754, here are decompositions:

101 + 31518653 = 31518754
107 + 31518647 = 31518754
233 + 31518521 = 31518754
263 + 31518491 = 31518754
401 + 31518353 = 31518754
467 + 31518287 = 31518754
557 + 31518197 = 31518754
1031 + 31517723 = 31518754

Showing the first eight; more decompositions exist.
