Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586174, here are decompositions:

3 + 31586171 = 31586174
43 + 31586131 = 31586174
73 + 31586101 = 31586174
97 + 31586077 = 31586174
211 + 31585963 = 31586174
271 + 31585903 = 31586174
337 + 31585837 = 31586174
397 + 31585777 = 31586174

Showing the first eight; more decompositions exist.
