Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99478, here are decompositions:
- 47 + 99431 = 99478
- 101 + 99377 = 99478
- 107 + 99371 = 99478
- 131 + 99347 = 99478
- 227 + 99251 = 99478
- 347 + 99131 = 99478
- 359 + 99119 = 99478
- 389 + 99089 = 99478
Showing the first eight; more decompositions exist.
