Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586804, here are decompositions:

13 + 31586791 = 31586804
61 + 31586743 = 31586804
97 + 31586707 = 31586804
157 + 31586647 = 31586804
307 + 31586497 = 31586804
331 + 31586473 = 31586804
397 + 31586407 = 31586804
523 + 31586281 = 31586804

Showing the first eight; more decompositions exist.
