Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71850, here are decompositions:
- 7 + 71843 = 71850
- 13 + 71837 = 71850
- 29 + 71821 = 71850
- 41 + 71809 = 71850
- 43 + 71807 = 71850
- 61 + 71789 = 71850
- 73 + 71777 = 71850
- 89 + 71761 = 71850
Showing the first eight; more decompositions exist.
