Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169972, here are decompositions:
- 29 + 169943 = 169972
- 53 + 169919 = 169972
- 59 + 169913 = 169972
- 83 + 169889 = 169972
- 113 + 169859 = 169972
- 149 + 169823 = 169972
- 239 + 169733 = 169972
- 263 + 169709 = 169972
Showing the first eight; more decompositions exist.
