Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586504, here are decompositions:

3 + 31586501 = 31586504
7 + 31586497 = 31586504
31 + 31586473 = 31586504
43 + 31586461 = 31586504
97 + 31586407 = 31586504
127 + 31586377 = 31586504
193 + 31586311 = 31586504
223 + 31586281 = 31586504

Showing the first eight; more decompositions exist.
