Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526972, here are decompositions:
- 19 + 31526953 = 31526972
- 31 + 31526941 = 31526972
- 73 + 31526899 = 31526972
- 79 + 31526893 = 31526972
- 109 + 31526863 = 31526972
- 163 + 31526809 = 31526972
- 181 + 31526791 = 31526972
- 199 + 31526773 = 31526972
Showing the first eight; more decompositions exist.
