Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586552, here are decompositions:

43 + 31586509 = 31586552
79 + 31586473 = 31586552
241 + 31586311 = 31586552
271 + 31586281 = 31586552
421 + 31586131 = 31586552
499 + 31586053 = 31586552
769 + 31585783 = 31586552
1051 + 31585501 = 31586552

Showing the first eight; more decompositions exist.
