Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546220, here are decompositions:
- 3 + 31546217 = 31546220
- 61 + 31546159 = 31546220
- 67 + 31546153 = 31546220
- 109 + 31546111 = 31546220
- 151 + 31546069 = 31546220
- 157 + 31546063 = 31546220
- 229 + 31545991 = 31546220
- 379 + 31545841 = 31546220
Showing the first eight; more decompositions exist.
