Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538264, here are decompositions:
- 3 + 31538261 = 31538264
- 13 + 31538251 = 31538264
- 61 + 31538203 = 31538264
- 103 + 31538161 = 31538264
- 127 + 31538137 = 31538264
- 151 + 31538113 = 31538264
- 157 + 31538107 = 31538264
- 193 + 31538071 = 31538264
Showing the first eight; more decompositions exist.
