Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163418, here are decompositions:
- 7 + 163411 = 163418
- 67 + 163351 = 163418
- 97 + 163321 = 163418
- 109 + 163309 = 163418
- 271 + 163147 = 163418
- 397 + 163021 = 163418
- 421 + 162997 = 163418
- 571 + 162847 = 163418
Showing the first eight; more decompositions exist.
