Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467902, here are decompositions:

3 + 31467899 = 31467902
73 + 31467829 = 31467902
139 + 31467763 = 31467902
181 + 31467721 = 31467902
211 + 31467691 = 31467902
313 + 31467589 = 31467902
331 + 31467571 = 31467902
421 + 31467481 = 31467902

Showing the first eight; more decompositions exist.
