Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31340, here are decompositions:
- 3 + 31337 = 31340
- 7 + 31333 = 31340
- 13 + 31327 = 31340
- 19 + 31321 = 31340
- 73 + 31267 = 31340
- 103 + 31237 = 31340
- 109 + 31231 = 31340
- 151 + 31189 = 31340
Showing the first eight; more decompositions exist.
