Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71458, here are decompositions:
- 5 + 71453 = 71458
- 29 + 71429 = 71458
- 47 + 71411 = 71458
- 59 + 71399 = 71458
- 71 + 71387 = 71458
- 131 + 71327 = 71458
- 197 + 71261 = 71458
- 311 + 71147 = 71458
Showing the first eight; more decompositions exist.
