Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589876, here are decompositions:

7 + 31589869 = 31589876
103 + 31589773 = 31589876
139 + 31589737 = 31589876
193 + 31589683 = 31589876
337 + 31589539 = 31589876
499 + 31589377 = 31589876
523 + 31589353 = 31589876
547 + 31589329 = 31589876

Showing the first eight; more decompositions exist.
