Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61572, here are decompositions:
- 11 + 61561 = 61572
- 13 + 61559 = 61572
- 19 + 61553 = 61572
- 29 + 61543 = 61572
- 53 + 61519 = 61572
- 61 + 61511 = 61572
- 79 + 61493 = 61572
- 89 + 61483 = 61572
Showing the first eight; more decompositions exist.
