Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80520, here are decompositions:
- 7 + 80513 = 80520
- 29 + 80491 = 80520
- 31 + 80489 = 80520
- 47 + 80473 = 80520
- 71 + 80449 = 80520
- 73 + 80447 = 80520
- 113 + 80407 = 80520
- 151 + 80369 = 80520
Showing the first eight; more decompositions exist.
