Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72206, here are decompositions:
- 37 + 72169 = 72206
- 67 + 72139 = 72206
- 97 + 72109 = 72206
- 103 + 72103 = 72206
- 163 + 72043 = 72206
- 223 + 71983 = 72206
- 307 + 71899 = 72206
- 397 + 71809 = 72206
Showing the first eight; more decompositions exist.
