Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042272, here are decompositions:
- 5 + 1042267 = 1042272
- 13 + 1042259 = 1042272
- 29 + 1042243 = 1042272
- 31 + 1042241 = 1042272
- 61 + 1042211 = 1042272
- 79 + 1042193 = 1042272
- 89 + 1042183 = 1042272
- 131 + 1042141 = 1042272
Showing the first eight; more decompositions exist.
