Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71956, here are decompositions:
- 23 + 71933 = 71956
- 47 + 71909 = 71956
- 89 + 71867 = 71956
- 107 + 71849 = 71956
- 113 + 71843 = 71956
- 149 + 71807 = 71956
- 167 + 71789 = 71956
- 179 + 71777 = 71956
Showing the first eight; more decompositions exist.
