Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543546, here are decompositions:

3 + 31543543 = 31543546
17 + 31543529 = 31543546
149 + 31543397 = 31543546
197 + 31543349 = 31543546
383 + 31543163 = 31543546
443 + 31543103 = 31543546
467 + 31543079 = 31543546
479 + 31543067 = 31543546

Showing the first eight; more decompositions exist.
