Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504676, here are decompositions:

103 + 31504573 = 31504676
109 + 31504567 = 31504676
223 + 31504453 = 31504676
349 + 31504327 = 31504676
373 + 31504303 = 31504676
457 + 31504219 = 31504676
487 + 31504189 = 31504676
547 + 31504129 = 31504676

Showing the first eight; more decompositions exist.
