Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79438, here are decompositions:
- 5 + 79433 = 79438
- 11 + 79427 = 79438
- 41 + 79397 = 79438
- 59 + 79379 = 79438
- 71 + 79367 = 79438
- 89 + 79349 = 79438
- 101 + 79337 = 79438
- 137 + 79301 = 79438
Showing the first eight; more decompositions exist.
