Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179478, here are decompositions:
- 7 + 179471 = 179478
- 17 + 179461 = 179478
- 37 + 179441 = 179478
- 41 + 179437 = 179478
- 67 + 179411 = 179478
- 71 + 179407 = 179478
- 97 + 179381 = 179478
- 109 + 179369 = 179478
Showing the first eight; more decompositions exist.
