Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61500, here are decompositions:
- 7 + 61493 = 61500
- 13 + 61487 = 61500
- 17 + 61483 = 61500
- 29 + 61471 = 61500
- 31 + 61469 = 61500
- 37 + 61463 = 61500
- 59 + 61441 = 61500
- 83 + 61417 = 61500
Showing the first eight; more decompositions exist.
