Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31300, here are decompositions:
- 23 + 31277 = 31300
- 29 + 31271 = 31300
- 41 + 31259 = 31300
- 47 + 31253 = 31300
- 53 + 31247 = 31300
- 107 + 31193 = 31300
- 149 + 31151 = 31300
- 179 + 31121 = 31300
Showing the first eight; more decompositions exist.
