Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61550, here are decompositions:
- 3 + 61547 = 61550
- 7 + 61543 = 61550
- 31 + 61519 = 61550
- 43 + 61507 = 61550
- 67 + 61483 = 61550
- 79 + 61471 = 61550
- 109 + 61441 = 61550
- 193 + 61357 = 61550
Showing the first eight; more decompositions exist.
