Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75072, here are decompositions:
- 31 + 75041 = 75072
- 43 + 75029 = 75072
- 59 + 75013 = 75072
- 61 + 75011 = 75072
- 113 + 74959 = 75072
- 131 + 74941 = 75072
- 139 + 74933 = 75072
- 149 + 74923 = 75072
Showing the first eight; more decompositions exist.
