Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742212, here are decompositions:
- 19 + 8742193 = 8742212
- 43 + 8742169 = 8742212
- 79 + 8742133 = 8742212
- 109 + 8742103 = 8742212
- 223 + 8741989 = 8742212
- 229 + 8741983 = 8742212
- 373 + 8741839 = 8742212
- 433 + 8741779 = 8742212
Showing the first eight; more decompositions exist.
