Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722272, here are decompositions:
- 61 + 8722211 = 8722272
- 79 + 8722193 = 8722272
- 101 + 8722171 = 8722272
- 103 + 8722169 = 8722272
- 149 + 8722123 = 8722272
- 173 + 8722099 = 8722272
- 179 + 8722093 = 8722272
- 191 + 8722081 = 8722272
Showing the first eight; more decompositions exist.
