Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023390, here are decompositions:
- 23 + 1023367 = 1023390
- 29 + 1023361 = 1023390
- 37 + 1023353 = 1023390
- 61 + 1023329 = 1023390
- 73 + 1023317 = 1023390
- 79 + 1023311 = 1023390
- 89 + 1023301 = 1023390
- 101 + 1023289 = 1023390
Showing the first eight; more decompositions exist.
