Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589792, here are decompositions:

19 + 31589773 = 31589792
61 + 31589731 = 31589792
109 + 31589683 = 31589792
181 + 31589611 = 31589792
331 + 31589461 = 31589792
433 + 31589359 = 31589792
439 + 31589353 = 31589792
463 + 31589329 = 31589792

Showing the first eight; more decompositions exist.
