Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589758, here are decompositions:

47 + 31589711 = 31589758
191 + 31589567 = 31589758
197 + 31589561 = 31589758
419 + 31589339 = 31589758
461 + 31589297 = 31589758
467 + 31589291 = 31589758
659 + 31589099 = 31589758
701 + 31589057 = 31589758

Showing the first eight; more decompositions exist.
