Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502258, here are decompositions:

97 + 31502161 = 31502258
127 + 31502131 = 31502258
379 + 31501879 = 31502258
397 + 31501861 = 31502258
409 + 31501849 = 31502258
439 + 31501819 = 31502258
499 + 31501759 = 31502258
691 + 31501567 = 31502258

Showing the first eight; more decompositions exist.
