Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72500, here are decompositions:
- 3 + 72497 = 72500
- 7 + 72493 = 72500
- 19 + 72481 = 72500
- 31 + 72469 = 72500
- 79 + 72421 = 72500
- 163 + 72337 = 72500
- 193 + 72307 = 72500
- 223 + 72277 = 72500
Showing the first eight; more decompositions exist.
