Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478626, here are decompositions:
- 59 + 31478567 = 31478626
- 197 + 31478429 = 31478626
- 227 + 31478399 = 31478626
- 233 + 31478393 = 31478626
- 293 + 31478333 = 31478626
- 317 + 31478309 = 31478626
- 359 + 31478267 = 31478626
- 479 + 31478147 = 31478626
Showing the first eight; more decompositions exist.
