Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470494, here are decompositions:
- 157 + 31470337 = 31470494
- 271 + 31470223 = 31470494
- 277 + 31470217 = 31470494
- 397 + 31470097 = 31470494
- 421 + 31470073 = 31470494
- 457 + 31470037 = 31470494
- 541 + 31469953 = 31470494
- 571 + 31469923 = 31470494
Showing the first eight; more decompositions exist.
