Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164408, here are decompositions:
- 31 + 164377 = 164408
- 37 + 164371 = 164408
- 67 + 164341 = 164408
- 109 + 164299 = 164408
- 157 + 164251 = 164408
- 199 + 164209 = 164408
- 337 + 164071 = 164408
- 397 + 164011 = 164408
Showing the first eight; more decompositions exist.
