Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467860, here are decompositions:

7 + 31467853 = 31467860
13 + 31467847 = 31467860
31 + 31467829 = 31467860
97 + 31467763 = 31467860
139 + 31467721 = 31467860
271 + 31467589 = 31467860
379 + 31467481 = 31467860
601 + 31467259 = 31467860

Showing the first eight; more decompositions exist.
