Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532992, here are decompositions:

11 + 31532981 = 31532992
53 + 31532939 = 31532992
353 + 31532639 = 31532992
419 + 31532573 = 31532992
503 + 31532489 = 31532992
563 + 31532429 = 31532992
653 + 31532339 = 31532992
773 + 31532219 = 31532992

Showing the first eight; more decompositions exist.
