Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71328, here are decompositions:
- 11 + 71317 = 71328
- 41 + 71287 = 71328
- 67 + 71261 = 71328
- 71 + 71257 = 71328
- 79 + 71249 = 71328
- 137 + 71191 = 71328
- 157 + 71171 = 71328
- 167 + 71161 = 71328
Showing the first eight; more decompositions exist.
