Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447610, here are decompositions:

3 + 31447607 = 31447610
37 + 31447573 = 31447610
277 + 31447333 = 31447610
421 + 31447189 = 31447610
541 + 31447069 = 31447610
613 + 31446997 = 31447610
661 + 31446949 = 31447610
673 + 31446937 = 31447610

Showing the first eight; more decompositions exist.
