Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61392, here are decompositions:
- 11 + 61381 = 61392
- 13 + 61379 = 61392
- 29 + 61363 = 61392
- 53 + 61339 = 61392
- 59 + 61333 = 61392
- 61 + 61331 = 61392
- 101 + 61291 = 61392
- 109 + 61283 = 61392
Showing the first eight; more decompositions exist.
