Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61372, here are decompositions:
- 29 + 61343 = 61372
- 41 + 61331 = 61372
- 89 + 61283 = 61372
- 149 + 61223 = 61372
- 251 + 61121 = 61372
- 281 + 61091 = 61372
- 419 + 60953 = 61372
- 449 + 60923 = 61372
Showing the first eight; more decompositions exist.
