Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43148, here are decompositions:
- 31 + 43117 = 43148
- 97 + 43051 = 43148
- 181 + 42967 = 43148
- 211 + 42937 = 43148
- 307 + 42841 = 43148
- 397 + 42751 = 43148
- 421 + 42727 = 43148
- 439 + 42709 = 43148
Showing the first eight; more decompositions exist.
