Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470652, here are decompositions:

11 + 31470641 = 31470652
23 + 31470629 = 31470652
29 + 31470623 = 31470652
71 + 31470581 = 31470652
89 + 31470563 = 31470652
293 + 31470359 = 31470652
359 + 31470293 = 31470652
431 + 31470221 = 31470652

Showing the first eight; more decompositions exist.
