Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77870, here are decompositions:
- 3 + 77867 = 77870
- 7 + 77863 = 77870
- 31 + 77839 = 77870
- 73 + 77797 = 77870
- 97 + 77773 = 77870
- 109 + 77761 = 77870
- 127 + 77743 = 77870
- 139 + 77731 = 77870
Showing the first eight; more decompositions exist.
