Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477422, here are decompositions:

23 + 31477399 = 31477422
43 + 31477379 = 31477422
71 + 31477351 = 31477422
73 + 31477349 = 31477422
101 + 31477321 = 31477422
131 + 31477291 = 31477422
241 + 31477181 = 31477422
281 + 31477141 = 31477422

Showing the first eight; more decompositions exist.
