Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532622, here are decompositions:

29 + 31532593 = 31532622
41 + 31532581 = 31532622
71 + 31532551 = 31532622
83 + 31532539 = 31532622
101 + 31532521 = 31532622
193 + 31532429 = 31532622
269 + 31532353 = 31532622
281 + 31532341 = 31532622

Showing the first eight; more decompositions exist.
