Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470566, here are decompositions:

3 + 31470563 = 31470566
19 + 31470547 = 31470566
97 + 31470469 = 31470566
157 + 31470409 = 31470566
229 + 31470337 = 31470566
307 + 31470259 = 31470566
349 + 31470217 = 31470566
367 + 31470199 = 31470566

Showing the first eight; more decompositions exist.
