Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148428, here are decompositions:
- 17 + 148411 = 148428
- 29 + 148399 = 148428
- 41 + 148387 = 148428
- 47 + 148381 = 148428
- 61 + 148367 = 148428
- 67 + 148361 = 148428
- 89 + 148339 = 148428
- 97 + 148331 = 148428
Showing the first eight; more decompositions exist.
