Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31250, here are decompositions:
- 3 + 31247 = 31250
- 13 + 31237 = 31250
- 19 + 31231 = 31250
- 31 + 31219 = 31250
- 61 + 31189 = 31250
- 67 + 31183 = 31250
- 73 + 31177 = 31250
- 97 + 31153 = 31250
Showing the first eight; more decompositions exist.
