Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534002, here are decompositions:
- 23 + 31533979 = 31534002
- 43 + 31533959 = 31534002
- 53 + 31533949 = 31534002
- 79 + 31533923 = 31534002
- 83 + 31533919 = 31534002
- 131 + 31533871 = 31534002
- 163 + 31533839 = 31534002
- 173 + 31533829 = 31534002
Showing the first eight; more decompositions exist.
