Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540152, here are decompositions:
- 5 + 31540147 = 31540152
- 29 + 31540123 = 31540152
- 43 + 31540109 = 31540152
- 53 + 31540099 = 31540152
- 89 + 31540063 = 31540152
- 139 + 31540013 = 31540152
- 181 + 31539971 = 31540152
- 251 + 31539901 = 31540152
Showing the first eight; more decompositions exist.
