Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172260, here are decompositions:
- 17 + 172243 = 172260
- 37 + 172223 = 172260
- 41 + 172219 = 172260
- 43 + 172217 = 172260
- 47 + 172213 = 172260
- 61 + 172199 = 172260
- 79 + 172181 = 172260
- 89 + 172171 = 172260
Showing the first eight; more decompositions exist.
