Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453844, here are decompositions:

3 + 31453841 = 31453844
31 + 31453813 = 31453844
61 + 31453783 = 31453844
193 + 31453651 = 31453844
337 + 31453507 = 31453844
397 + 31453447 = 31453844
523 + 31453321 = 31453844
577 + 31453267 = 31453844

Showing the first eight; more decompositions exist.
