Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161470, here are decompositions:
- 11 + 161459 = 161470
- 17 + 161453 = 161470
- 59 + 161411 = 161470
- 83 + 161387 = 161470
- 107 + 161363 = 161470
- 131 + 161339 = 161470
- 137 + 161333 = 161470
- 167 + 161303 = 161470
Showing the first eight; more decompositions exist.
