Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148816, here are decompositions:
- 23 + 148793 = 148816
- 53 + 148763 = 148816
- 89 + 148727 = 148816
- 149 + 148667 = 148816
- 347 + 148469 = 148816
- 359 + 148457 = 148816
- 449 + 148367 = 148816
- 587 + 148229 = 148816
Showing the first eight; more decompositions exist.
