Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615680, here are decompositions:
- 13 + 33615667 = 33615680
- 19 + 33615661 = 33615680
- 31 + 33615649 = 33615680
- 37 + 33615643 = 33615680
- 73 + 33615607 = 33615680
- 79 + 33615601 = 33615680
- 97 + 33615583 = 33615680
- 157 + 33615523 = 33615680
Showing the first eight; more decompositions exist.
