Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61566, here are decompositions:
- 5 + 61561 = 61566
- 7 + 61559 = 61566
- 13 + 61553 = 61566
- 19 + 61547 = 61566
- 23 + 61543 = 61566
- 47 + 61519 = 61566
- 59 + 61507 = 61566
- 73 + 61493 = 61566
Showing the first eight; more decompositions exist.
