Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495692, here are decompositions:
- 29 + 31495663 = 31495692
- 31 + 31495661 = 31495692
- 89 + 31495603 = 31495692
- 101 + 31495591 = 31495692
- 103 + 31495589 = 31495692
- 181 + 31495511 = 31495692
- 191 + 31495501 = 31495692
- 199 + 31495493 = 31495692
Showing the first eight; more decompositions exist.
