Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589948, here are decompositions:

79 + 31589869 = 31589948
211 + 31589737 = 31589948
241 + 31589707 = 31589948
337 + 31589611 = 31589948
409 + 31589539 = 31589948
487 + 31589461 = 31589948
541 + 31589407 = 31589948
547 + 31589401 = 31589948

Showing the first eight; more decompositions exist.
