Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470760, here are decompositions:

59 + 31470701 = 31470760
107 + 31470653 = 31470760
131 + 31470629 = 31470760
137 + 31470623 = 31470760
179 + 31470581 = 31470760
197 + 31470563 = 31470760
317 + 31470443 = 31470760
401 + 31470359 = 31470760

Showing the first eight; more decompositions exist.
