Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586232, here are decompositions:

61 + 31586171 = 31586232
101 + 31586131 = 31586232
131 + 31586101 = 31586232
173 + 31586059 = 31586232
179 + 31586053 = 31586232
229 + 31586003 = 31586232
269 + 31585963 = 31586232
383 + 31585849 = 31586232

Showing the first eight; more decompositions exist.
