Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565042, here are decompositions:
- 13 + 31565029 = 31565042
- 109 + 31564933 = 31565042
- 151 + 31564891 = 31565042
- 163 + 31564879 = 31565042
- 193 + 31564849 = 31565042
- 211 + 31564831 = 31565042
- 373 + 31564669 = 31565042
- 541 + 31564501 = 31565042
Showing the first eight; more decompositions exist.
