Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023420, here are decompositions:
- 7 + 1023413 = 1023420
- 11 + 1023409 = 1023420
- 29 + 1023391 = 1023420
- 31 + 1023389 = 1023420
- 53 + 1023367 = 1023420
- 59 + 1023361 = 1023420
- 67 + 1023353 = 1023420
- 103 + 1023317 = 1023420
Showing the first eight; more decompositions exist.
