Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534994, here are decompositions:

13 + 31534981 = 31534994
163 + 31534831 = 31534994
193 + 31534801 = 31534994
241 + 31534753 = 31534994
397 + 31534597 = 31534994
433 + 31534561 = 31534994
571 + 31534423 = 31534994
661 + 31534333 = 31534994

Showing the first eight; more decompositions exist.
