Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545786, here are decompositions:
- 23 + 31545763 = 31545786
- 37 + 31545749 = 31545786
- 43 + 31545743 = 31545786
- 47 + 31545739 = 31545786
- 73 + 31545713 = 31545786
- 157 + 31545629 = 31545786
- 163 + 31545623 = 31545786
- 179 + 31545607 = 31545786
Showing the first eight; more decompositions exist.
