Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589012, here are decompositions:

19 + 31588993 = 31589012
61 + 31588951 = 31589012
79 + 31588933 = 31589012
199 + 31588813 = 31589012
313 + 31588699 = 31589012
409 + 31588603 = 31589012
541 + 31588471 = 31589012
571 + 31588441 = 31589012

Showing the first eight; more decompositions exist.
