Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469342, here are decompositions:
- 19 + 31469323 = 31469342
- 43 + 31469299 = 31469342
- 103 + 31469239 = 31469342
- 199 + 31469143 = 31469342
- 211 + 31469131 = 31469342
- 241 + 31469101 = 31469342
- 349 + 31468993 = 31469342
- 379 + 31468963 = 31469342
Showing the first eight; more decompositions exist.
