Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61636, here are decompositions:
- 5 + 61631 = 61636
- 23 + 61613 = 61636
- 53 + 61583 = 61636
- 83 + 61553 = 61636
- 89 + 61547 = 61636
- 149 + 61487 = 61636
- 167 + 61469 = 61636
- 173 + 61463 = 61636
Showing the first eight; more decompositions exist.
