Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470152, here are decompositions:

79 + 31470073 = 31470152
139 + 31470013 = 31470152
163 + 31469989 = 31470152
199 + 31469953 = 31470152
229 + 31469923 = 31470152
421 + 31469731 = 31470152
463 + 31469689 = 31470152
499 + 31469653 = 31470152

Showing the first eight; more decompositions exist.
