Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510248, here are decompositions:
- 5 + 31510243 = 31510248
- 31 + 31510217 = 31510248
- 61 + 31510187 = 31510248
- 79 + 31510169 = 31510248
- 109 + 31510139 = 31510248
- 127 + 31510121 = 31510248
- 137 + 31510111 = 31510248
- 157 + 31510091 = 31510248
Showing the first eight; more decompositions exist.
