Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586244, here are decompositions:

7 + 31586237 = 31586244
73 + 31586171 = 31586244
97 + 31586147 = 31586244
103 + 31586141 = 31586244
113 + 31586131 = 31586244
167 + 31586077 = 31586244
191 + 31586053 = 31586244
241 + 31586003 = 31586244

Showing the first eight; more decompositions exist.
