Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61488, here are decompositions:
- 5 + 61483 = 61488
- 17 + 61471 = 61488
- 19 + 61469 = 61488
- 47 + 61441 = 61488
- 71 + 61417 = 61488
- 79 + 61409 = 61488
- 107 + 61381 = 61488
- 109 + 61379 = 61488
Showing the first eight; more decompositions exist.
