Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61398, here are decompositions:
- 17 + 61381 = 61398
- 19 + 61379 = 61398
- 41 + 61357 = 61398
- 59 + 61339 = 61398
- 67 + 61331 = 61398
- 101 + 61297 = 61398
- 107 + 61291 = 61398
- 137 + 61261 = 61398
Showing the first eight; more decompositions exist.
