Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42624, here are decompositions:
- 13 + 42611 = 42624
- 47 + 42577 = 42624
- 53 + 42571 = 42624
- 67 + 42557 = 42624
- 137 + 42487 = 42624
- 151 + 42473 = 42624
- 157 + 42467 = 42624
- 163 + 42461 = 42624
Showing the first eight; more decompositions exist.
