Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164538, here are decompositions:
- 7 + 164531 = 164538
- 61 + 164477 = 164538
- 67 + 164471 = 164538
- 89 + 164449 = 164538
- 107 + 164431 = 164538
- 109 + 164429 = 164538
- 151 + 164387 = 164538
- 167 + 164371 = 164538
Showing the first eight; more decompositions exist.
