Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536994, here are decompositions:

3 + 31536991 = 31536994
11 + 31536983 = 31536994
131 + 31536863 = 31536994
173 + 31536821 = 31536994
263 + 31536731 = 31536994
443 + 31536551 = 31536994
641 + 31536353 = 31536994
647 + 31536347 = 31536994

Showing the first eight; more decompositions exist.
