Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471762, here are decompositions:
- 59 + 31471703 = 31471762
- 239 + 31471523 = 31471762
- 251 + 31471511 = 31471762
- 281 + 31471481 = 31471762
- 293 + 31471469 = 31471762
- 389 + 31471373 = 31471762
- 401 + 31471361 = 31471762
- 431 + 31471331 = 31471762
Showing the first eight; more decompositions exist.
