Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40220, here are decompositions:
- 7 + 40213 = 40220
- 31 + 40189 = 40220
- 43 + 40177 = 40220
- 67 + 40153 = 40220
- 97 + 40123 = 40220
- 109 + 40111 = 40220
- 127 + 40093 = 40220
- 157 + 40063 = 40220
Showing the first eight; more decompositions exist.
