Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508626, here are decompositions:
- 5 + 31508621 = 31508626
- 47 + 31508579 = 31508626
- 59 + 31508567 = 31508626
- 173 + 31508453 = 31508626
- 263 + 31508363 = 31508626
- 449 + 31508177 = 31508626
- 467 + 31508159 = 31508626
- 587 + 31508039 = 31508626
Showing the first eight; more decompositions exist.
