Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149438, here are decompositions:
- 19 + 149419 = 149438
- 61 + 149377 = 149438
- 67 + 149371 = 149438
- 97 + 149341 = 149438
- 151 + 149287 = 149438
- 181 + 149257 = 149438
- 199 + 149239 = 149438
- 241 + 149197 = 149438
Showing the first eight; more decompositions exist.
