Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450, here are decompositions:
- 53 + 31397 = 31450
- 59 + 31391 = 31450
- 71 + 31379 = 31450
- 113 + 31337 = 31450
- 131 + 31319 = 31450
- 173 + 31277 = 31450
- 179 + 31271 = 31450
- 191 + 31259 = 31450
Showing the first eight; more decompositions exist.
