Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473782, here are decompositions:

3 + 31473779 = 31473782
79 + 31473703 = 31473782
199 + 31473583 = 31473782
499 + 31473283 = 31473782
541 + 31473241 = 31473782
619 + 31473163 = 31473782
631 + 31473151 = 31473782
673 + 31473109 = 31473782

Showing the first eight; more decompositions exist.
