Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025478, here are decompositions:
- 19 + 1025459 = 1025478
- 59 + 1025419 = 1025478
- 61 + 1025417 = 1025478
- 71 + 1025407 = 1025478
- 127 + 1025351 = 1025478
- 131 + 1025347 = 1025478
- 151 + 1025327 = 1025478
- 197 + 1025281 = 1025478
Showing the first eight; more decompositions exist.
