Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582260, here are decompositions:

11 + 31582249 = 31582260
19 + 31582241 = 31582260
43 + 31582217 = 31582260
53 + 31582207 = 31582260
67 + 31582193 = 31582260
89 + 31582171 = 31582260
97 + 31582163 = 31582260
139 + 31582121 = 31582260

Showing the first eight; more decompositions exist.
