Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586330, here are decompositions:

19 + 31586311 = 31586330
43 + 31586287 = 31586330
73 + 31586257 = 31586330
199 + 31586131 = 31586330
229 + 31586101 = 31586330
271 + 31586059 = 31586330
277 + 31586053 = 31586330
367 + 31585963 = 31586330

Showing the first eight; more decompositions exist.
