Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17438, here are decompositions:
- 7 + 17431 = 17438
- 19 + 17419 = 17438
- 37 + 17401 = 17438
- 61 + 17377 = 17438
- 79 + 17359 = 17438
- 97 + 17341 = 17438
- 139 + 17299 = 17438
- 181 + 17257 = 17438
Showing the first eight; more decompositions exist.
