Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2438, here are decompositions:
- 61 + 2377 = 2438
- 67 + 2371 = 2438
- 97 + 2341 = 2438
- 127 + 2311 = 2438
- 151 + 2287 = 2438
- 157 + 2281 = 2438
- 199 + 2239 = 2438
- 277 + 2161 = 2438
Showing the first eight; more decompositions exist.
