Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73644, here are decompositions:
- 7 + 73637 = 73644
- 31 + 73613 = 73644
- 37 + 73607 = 73644
- 47 + 73597 = 73644
- 61 + 73583 = 73644
- 73 + 73571 = 73644
- 83 + 73561 = 73644
- 97 + 73547 = 73644
Showing the first eight; more decompositions exist.
