Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541214, here are decompositions:
- 41 + 31541173 = 31541214
- 53 + 31541161 = 31541214
- 73 + 31541141 = 31541214
- 97 + 31541117 = 31541214
- 101 + 31541113 = 31541214
- 113 + 31541101 = 31541214
- 163 + 31541051 = 31541214
- 167 + 31541047 = 31541214
Showing the first eight; more decompositions exist.
