Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540328, here are decompositions:
- 19 + 31540309 = 31540328
- 31 + 31540297 = 31540328
- 67 + 31540261 = 31540328
- 139 + 31540189 = 31540328
- 181 + 31540147 = 31540328
- 229 + 31540099 = 31540328
- 397 + 31539931 = 31540328
- 439 + 31539889 = 31540328
Showing the first eight; more decompositions exist.
