Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541698, here are decompositions:
- 5 + 31541693 = 31541698
- 47 + 31541651 = 31541698
- 101 + 31541597 = 31541698
- 107 + 31541591 = 31541698
- 191 + 31541507 = 31541698
- 269 + 31541429 = 31541698
- 281 + 31541417 = 31541698
- 401 + 31541297 = 31541698
Showing the first eight; more decompositions exist.
