Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164486, here are decompositions:

37 + 164449 = 164486
43 + 164443 = 164486
67 + 164419 = 164486
73 + 164413 = 164486
109 + 164377 = 164486
277 + 164209 = 164486
313 + 164173 = 164486
337 + 164149 = 164486

Showing the first eight; more decompositions exist.
