Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554364, here are decompositions:

3 + 31554361 = 31554364
353 + 31554011 = 31554364
461 + 31553903 = 31554364
557 + 31553807 = 31554364
563 + 31553801 = 31554364
587 + 31553777 = 31554364
701 + 31553663 = 31554364
911 + 31553453 = 31554364

Showing the first eight; more decompositions exist.
