Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520520, here are decompositions:
- 31 + 33520489 = 33520520
- 43 + 33520477 = 33520520
- 151 + 33520369 = 33520520
- 157 + 33520363 = 33520520
- 199 + 33520321 = 33520520
- 373 + 33520147 = 33520520
- 433 + 33520087 = 33520520
- 457 + 33520063 = 33520520
Showing the first eight; more decompositions exist.
