Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79428, here are decompositions:
- 5 + 79423 = 79428
- 17 + 79411 = 79428
- 29 + 79399 = 79428
- 31 + 79397 = 79428
- 61 + 79367 = 79428
- 71 + 79357 = 79428
- 79 + 79349 = 79428
- 109 + 79319 = 79428
Showing the first eight; more decompositions exist.
