Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155282, here are decompositions:
- 13 + 155269 = 155282
- 31 + 155251 = 155282
- 73 + 155209 = 155282
- 79 + 155203 = 155282
- 163 + 155119 = 155282
- 199 + 155083 = 155282
- 349 + 154933 = 155282
- 409 + 154873 = 155282
Showing the first eight; more decompositions exist.
