Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535174, here are decompositions:
- 3 + 31535171 = 31535174
- 31 + 31535143 = 31535174
- 43 + 31535131 = 31535174
- 61 + 31535113 = 31535174
- 67 + 31535107 = 31535174
- 163 + 31535011 = 31535174
- 193 + 31534981 = 31535174
- 373 + 31534801 = 31535174
Showing the first eight; more decompositions exist.
