Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45428, here are decompositions:
- 67 + 45361 = 45428
- 109 + 45319 = 45428
- 139 + 45289 = 45428
- 181 + 45247 = 45428
- 307 + 45121 = 45428
- 367 + 45061 = 45428
- 421 + 45007 = 45428
- 457 + 44971 = 45428
Showing the first eight; more decompositions exist.
