Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61690, here are decompositions:
- 3 + 61687 = 61690
- 17 + 61673 = 61690
- 23 + 61667 = 61690
- 47 + 61643 = 61690
- 53 + 61637 = 61690
- 59 + 61631 = 61690
- 107 + 61583 = 61690
- 131 + 61559 = 61690
Showing the first eight; more decompositions exist.
