Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175438, here are decompositions:
- 5 + 175433 = 175438
- 47 + 175391 = 175438
- 89 + 175349 = 175438
- 227 + 175211 = 175438
- 359 + 175079 = 175438
- 449 + 174989 = 175438
- 479 + 174959 = 175438
- 509 + 174929 = 175438
Showing the first eight; more decompositions exist.
