Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61430, here are decompositions:
- 13 + 61417 = 61430
- 67 + 61363 = 61430
- 73 + 61357 = 61430
- 97 + 61333 = 61430
- 139 + 61291 = 61430
- 199 + 61231 = 61430
- 277 + 61153 = 61430
- 331 + 61099 = 61430
Showing the first eight; more decompositions exist.
