Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995720, here are decompositions:
- 7 + 995713 = 995720
- 43 + 995677 = 995720
- 79 + 995641 = 995720
- 97 + 995623 = 995720
- 109 + 995611 = 995720
- 127 + 995593 = 995720
- 181 + 995539 = 995720
- 277 + 995443 = 995720
Showing the first eight; more decompositions exist.
