Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527150, here are decompositions:
- 7 + 31527143 = 31527150
- 19 + 31527131 = 31527150
- 41 + 31527109 = 31527150
- 43 + 31527107 = 31527150
- 73 + 31527077 = 31527150
- 103 + 31527047 = 31527150
- 139 + 31527011 = 31527150
- 197 + 31526953 = 31527150
Showing the first eight; more decompositions exist.
