Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615780, here are decompositions:
- 7 + 33615773 = 33615780
- 13 + 33615767 = 33615780
- 19 + 33615761 = 33615780
- 41 + 33615739 = 33615780
- 43 + 33615737 = 33615780
- 67 + 33615713 = 33615780
- 73 + 33615707 = 33615780
- 109 + 33615671 = 33615780
Showing the first eight; more decompositions exist.
