Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454564, here are decompositions:

67 + 31454497 = 31454564
103 + 31454461 = 31454564
181 + 31454383 = 31454564
367 + 31454197 = 31454564
373 + 31454191 = 31454564
487 + 31454077 = 31454564
541 + 31454023 = 31454564
571 + 31453993 = 31454564

Showing the first eight; more decompositions exist.
