Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526990, here are decompositions:
- 37 + 31526953 = 31526990
- 97 + 31526893 = 31526990
- 109 + 31526881 = 31526990
- 127 + 31526863 = 31526990
- 181 + 31526809 = 31526990
- 199 + 31526791 = 31526990
- 241 + 31526749 = 31526990
- 277 + 31526713 = 31526990
Showing the first eight; more decompositions exist.
