Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470684, here are decompositions:

23 + 31470661 = 31470684
31 + 31470653 = 31470684
43 + 31470641 = 31470684
61 + 31470623 = 31470684
103 + 31470581 = 31470684
127 + 31470557 = 31470684
137 + 31470547 = 31470684
241 + 31470443 = 31470684

Showing the first eight; more decompositions exist.
