Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055390, here are decompositions:
- 3 + 1055387 = 1055390
- 19 + 1055371 = 1055390
- 31 + 1055359 = 1055390
- 43 + 1055347 = 1055390
- 139 + 1055251 = 1055390
- 157 + 1055233 = 1055390
- 199 + 1055191 = 1055390
- 223 + 1055167 = 1055390
Showing the first eight; more decompositions exist.
