Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470636, here are decompositions:

7 + 31470629 = 31470636
13 + 31470623 = 31470636
17 + 31470619 = 31470636
73 + 31470563 = 31470636
79 + 31470557 = 31470636
89 + 31470547 = 31470636
167 + 31470469 = 31470636
193 + 31470443 = 31470636

Showing the first eight; more decompositions exist.
