Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467800, here are decompositions:
- 37 + 31467763 = 31467800
- 73 + 31467727 = 31467800
- 79 + 31467721 = 31467800
- 109 + 31467691 = 31467800
- 211 + 31467589 = 31467800
- 229 + 31467571 = 31467800
- 241 + 31467559 = 31467800
- 367 + 31467433 = 31467800
Showing the first eight; more decompositions exist.
