Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615492, here are decompositions:
- 3 + 31615489 = 31615492
- 53 + 31615439 = 31615492
- 89 + 31615403 = 31615492
- 101 + 31615391 = 31615492
- 149 + 31615343 = 31615492
- 179 + 31615313 = 31615492
- 263 + 31615229 = 31615492
- 281 + 31615211 = 31615492
Showing the first eight; more decompositions exist.
