Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61650, here are decompositions:
- 7 + 61643 = 61650
- 13 + 61637 = 61650
- 19 + 61631 = 61650
- 23 + 61627 = 61650
- 37 + 61613 = 61650
- 41 + 61609 = 61650
- 47 + 61603 = 61650
- 67 + 61583 = 61650
Showing the first eight; more decompositions exist.
