Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164520, here are decompositions:

7 + 164513 = 164520
17 + 164503 = 164520
43 + 164477 = 164520
71 + 164449 = 164520
73 + 164447 = 164520
89 + 164431 = 164520
101 + 164419 = 164520
107 + 164413 = 164520

Showing the first eight; more decompositions exist.
