Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71380, here are decompositions:
- 17 + 71363 = 71380
- 41 + 71339 = 71380
- 47 + 71333 = 71380
- 53 + 71327 = 71380
- 131 + 71249 = 71380
- 227 + 71153 = 71380
- 233 + 71147 = 71380
- 251 + 71129 = 71380
Showing the first eight; more decompositions exist.
