Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527452, here are decompositions:

109 + 31527343 = 31527452
199 + 31527253 = 31527452
241 + 31527211 = 31527452
499 + 31526953 = 31527452
571 + 31526881 = 31527452
643 + 31526809 = 31527452
661 + 31526791 = 31527452
739 + 31526713 = 31527452

Showing the first eight; more decompositions exist.
