Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79212, here are decompositions:
- 11 + 79201 = 79212
- 19 + 79193 = 79212
- 31 + 79181 = 79212
- 53 + 79159 = 79212
- 59 + 79153 = 79212
- 61 + 79151 = 79212
- 73 + 79139 = 79212
- 79 + 79133 = 79212
Showing the first eight; more decompositions exist.
