Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452664, here are decompositions:
- 41 + 31452623 = 31452664
- 137 + 31452527 = 31452664
- 167 + 31452497 = 31452664
- 263 + 31452401 = 31452664
- 431 + 31452233 = 31452664
- 461 + 31452203 = 31452664
- 491 + 31452173 = 31452664
- 827 + 31451837 = 31452664
Showing the first eight; more decompositions exist.
