Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460644, here are decompositions:

107 + 31460537 = 31460644
353 + 31460291 = 31460644
797 + 31459847 = 31460644
911 + 31459733 = 31460644
947 + 31459697 = 31460644
977 + 31459667 = 31460644
983 + 31459661 = 31460644
1091 + 31459553 = 31460644

Showing the first eight; more decompositions exist.
