Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71584, here are decompositions:
- 47 + 71537 = 71584
- 101 + 71483 = 71584
- 113 + 71471 = 71584
- 131 + 71453 = 71584
- 173 + 71411 = 71584
- 197 + 71387 = 71584
- 251 + 71333 = 71584
- 257 + 71327 = 71584
Showing the first eight; more decompositions exist.
