Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495190, here are decompositions:
- 3 + 31495187 = 31495190
- 19 + 31495171 = 31495190
- 37 + 31495153 = 31495190
- 43 + 31495147 = 31495190
- 73 + 31495117 = 31495190
- 127 + 31495063 = 31495190
- 211 + 31494979 = 31495190
- 241 + 31494949 = 31495190
Showing the first eight; more decompositions exist.
