Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61388, here are decompositions:
- 7 + 61381 = 61388
- 31 + 61357 = 61388
- 97 + 61291 = 61388
- 127 + 61261 = 61388
- 157 + 61231 = 61388
- 331 + 61057 = 61388
- 337 + 61051 = 61388
- 487 + 60901 = 61388
Showing the first eight; more decompositions exist.
