Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447526, here are decompositions:

163 + 31447363 = 31447526
193 + 31447333 = 31447526
337 + 31447189 = 31447526
457 + 31447069 = 31447526
499 + 31447027 = 31447526
577 + 31446949 = 31447526
673 + 31446853 = 31447526
757 + 31446769 = 31447526

Showing the first eight; more decompositions exist.
