Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589980, here are decompositions:

3 + 31589977 = 31589980
89 + 31589891 = 31589980
113 + 31589867 = 31589980
137 + 31589843 = 31589980
269 + 31589711 = 31589980
347 + 31589633 = 31589980
419 + 31589561 = 31589980
467 + 31589513 = 31589980

Showing the first eight; more decompositions exist.
