Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42272, here are decompositions:
- 79 + 42193 = 42272
- 103 + 42169 = 42272
- 199 + 42073 = 42272
- 211 + 42061 = 42272
- 229 + 42043 = 42272
- 313 + 41959 = 42272
- 331 + 41941 = 42272
- 379 + 41893 = 42272
Showing the first eight; more decompositions exist.
