Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173438, here are decompositions:
- 7 + 173431 = 173438
- 79 + 173359 = 173438
- 229 + 173209 = 173438
- 379 + 173059 = 173438
- 439 + 172999 = 173438
- 457 + 172981 = 173438
- 571 + 172867 = 173438
- 631 + 172807 = 173438
Showing the first eight; more decompositions exist.
