Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545874, here are decompositions:
- 131 + 31545743 = 31545874
- 137 + 31545737 = 31545874
- 233 + 31545641 = 31545874
- 251 + 31545623 = 31545874
- 263 + 31545611 = 31545874
- 467 + 31545407 = 31545874
- 557 + 31545317 = 31545874
- 587 + 31545287 = 31545874
Showing the first eight; more decompositions exist.
