Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545994, here are decompositions:
- 3 + 31545991 = 31545994
- 41 + 31545953 = 31545994
- 71 + 31545923 = 31545994
- 107 + 31545887 = 31545994
- 251 + 31545743 = 31545994
- 257 + 31545737 = 31545994
- 281 + 31545713 = 31545994
- 353 + 31545641 = 31545994
Showing the first eight; more decompositions exist.
