Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502254, here are decompositions:

11 + 31502243 = 31502254
41 + 31502213 = 31502254
71 + 31502183 = 31502254
107 + 31502147 = 31502254
317 + 31501937 = 31502254
347 + 31501907 = 31502254
431 + 31501823 = 31502254
503 + 31501751 = 31502254

Showing the first eight; more decompositions exist.
