Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25238, here are decompositions:
- 19 + 25219 = 25238
- 67 + 25171 = 25238
- 127 + 25111 = 25238
- 151 + 25087 = 25238
- 181 + 25057 = 25238
- 271 + 24967 = 25238
- 331 + 24907 = 25238
- 349 + 24889 = 25238
Showing the first eight; more decompositions exist.
