Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164890, here are decompositions:

53 + 164837 = 164890
59 + 164831 = 164890
101 + 164789 = 164890
227 + 164663 = 164890
263 + 164627 = 164890
269 + 164621 = 164890
359 + 164531 = 164890
419 + 164471 = 164890

Showing the first eight; more decompositions exist.
