Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025242, here are decompositions:
- 3 + 1025239 = 1025242
- 11 + 1025231 = 1025242
- 89 + 1025153 = 1025242
- 131 + 1025111 = 1025242
- 149 + 1025093 = 1025242
- 233 + 1025009 = 1025242
- 311 + 1024931 = 1025242
- 359 + 1024883 = 1025242
Showing the first eight; more decompositions exist.
