Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467644, here are decompositions:

73 + 31467571 = 31467644
163 + 31467481 = 31467644
211 + 31467433 = 31467644
277 + 31467367 = 31467644
463 + 31467181 = 31467644
487 + 31467157 = 31467644
541 + 31467103 = 31467644
577 + 31467067 = 31467644

Showing the first eight; more decompositions exist.
