Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607710, here are decompositions:
- 23 + 31607687 = 31607710
- 131 + 31607579 = 31607710
- 179 + 31607531 = 31607710
- 263 + 31607447 = 31607710
- 311 + 31607399 = 31607710
- 347 + 31607363 = 31607710
- 353 + 31607357 = 31607710
- 383 + 31607327 = 31607710
Showing the first eight; more decompositions exist.
