Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589282, here are decompositions:

31 + 31589251 = 31589282
163 + 31589119 = 31589282
271 + 31589011 = 31589282
331 + 31588951 = 31589282
349 + 31588933 = 31589282
811 + 31588471 = 31589282
883 + 31588399 = 31589282
1153 + 31588129 = 31589282

Showing the first eight; more decompositions exist.
