Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454522, here are decompositions:

61 + 31454461 = 31454522
139 + 31454383 = 31454522
331 + 31454191 = 31454522
373 + 31454149 = 31454522
439 + 31454083 = 31454522
499 + 31454023 = 31454522
613 + 31453909 = 31454522
643 + 31453879 = 31454522

Showing the first eight; more decompositions exist.
