Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16238, here are decompositions:
- 7 + 16231 = 16238
- 97 + 16141 = 16238
- 127 + 16111 = 16238
- 151 + 16087 = 16238
- 181 + 16057 = 16238
- 331 + 15907 = 16238
- 337 + 15901 = 16238
- 349 + 15889 = 16238
Showing the first eight; more decompositions exist.
