Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531624, here are decompositions:
- 101 + 31531523 = 31531624
- 167 + 31531457 = 31531624
- 353 + 31531271 = 31531624
- 461 + 31531163 = 31531624
- 647 + 31530977 = 31531624
- 797 + 31530827 = 31531624
- 827 + 31530797 = 31531624
- 911 + 31530713 = 31531624
Showing the first eight; more decompositions exist.
