Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502228, here are decompositions:

67 + 31502161 = 31502228
97 + 31502131 = 31502228
271 + 31501957 = 31502228
349 + 31501879 = 31502228
367 + 31501861 = 31502228
379 + 31501849 = 31502228
397 + 31501831 = 31502228
409 + 31501819 = 31502228

Showing the first eight; more decompositions exist.
