Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502260, here are decompositions:

17 + 31502243 = 31502260
47 + 31502213 = 31502260
71 + 31502189 = 31502260
113 + 31502147 = 31502260
131 + 31502129 = 31502260
281 + 31501979 = 31502260
347 + 31501913 = 31502260
353 + 31501907 = 31502260

Showing the first eight; more decompositions exist.
