Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470998, here are decompositions:
- 7 + 31470991 = 31470998
- 109 + 31470889 = 31470998
- 151 + 31470847 = 31470998
- 199 + 31470799 = 31470998
- 211 + 31470787 = 31470998
- 277 + 31470721 = 31470998
- 337 + 31470661 = 31470998
- 379 + 31470619 = 31470998
Showing the first eight; more decompositions exist.
