Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471046, here are decompositions:
- 3 + 31471043 = 31471046
- 157 + 31470889 = 31471046
- 193 + 31470853 = 31471046
- 199 + 31470847 = 31471046
- 223 + 31470823 = 31471046
- 337 + 31470709 = 31471046
- 499 + 31470547 = 31471046
- 577 + 31470469 = 31471046
Showing the first eight; more decompositions exist.
