Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582302, here are decompositions:

53 + 31582249 = 31582302
61 + 31582241 = 31582302
109 + 31582193 = 31582302
131 + 31582171 = 31582302
139 + 31582163 = 31582302
181 + 31582121 = 31582302
281 + 31582021 = 31582302
419 + 31581883 = 31582302

Showing the first eight; more decompositions exist.
