Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61428, here are decompositions:
- 11 + 61417 = 61428
- 19 + 61409 = 61428
- 47 + 61381 = 61428
- 71 + 61357 = 61428
- 89 + 61339 = 61428
- 97 + 61331 = 61428
- 131 + 61297 = 61428
- 137 + 61291 = 61428
Showing the first eight; more decompositions exist.
