Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72010, here are decompositions:
- 11 + 71999 = 72010
- 17 + 71993 = 72010
- 23 + 71987 = 72010
- 47 + 71963 = 72010
- 101 + 71909 = 72010
- 131 + 71879 = 72010
- 149 + 71861 = 72010
- 167 + 71843 = 72010
Showing the first eight; more decompositions exist.
