Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589258, here are decompositions:

7 + 31589251 = 31589258
61 + 31589197 = 31589258
139 + 31589119 = 31589258
241 + 31589017 = 31589258
307 + 31588951 = 31589258
331 + 31588927 = 31589258
601 + 31588657 = 31589258
787 + 31588471 = 31589258

Showing the first eight; more decompositions exist.
