Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61378, here are decompositions:
- 47 + 61331 = 61378
- 167 + 61211 = 61378
- 227 + 61151 = 61378
- 257 + 61121 = 61378
- 347 + 61031 = 61378
- 461 + 60917 = 61378
- 479 + 60899 = 61378
- 491 + 60887 = 61378
Showing the first eight; more decompositions exist.
