Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71504, here are decompositions:
- 31 + 71473 = 71504
- 61 + 71443 = 71504
- 67 + 71437 = 71504
- 151 + 71353 = 71504
- 157 + 71347 = 71504
- 163 + 71341 = 71504
- 211 + 71293 = 71504
- 241 + 71263 = 71504
Showing the first eight; more decompositions exist.
