Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61418, here are decompositions:
- 37 + 61381 = 61418
- 61 + 61357 = 61418
- 79 + 61339 = 61418
- 127 + 61291 = 61418
- 157 + 61261 = 61418
- 277 + 61141 = 61418
- 367 + 61051 = 61418
- 457 + 60961 = 61418
Showing the first eight; more decompositions exist.
