Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164744, here are decompositions:
- 37 + 164707 = 164744
- 43 + 164701 = 164744
- 61 + 164683 = 164744
- 67 + 164677 = 164744
- 127 + 164617 = 164744
- 157 + 164587 = 164744
- 163 + 164581 = 164744
- 241 + 164503 = 164744
Showing the first eight; more decompositions exist.
