Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536194, here are decompositions:

7 + 31536187 = 31536194
97 + 31536097 = 31536194
211 + 31535983 = 31536194
367 + 31535827 = 31536194
373 + 31535821 = 31536194
397 + 31535797 = 31536194
523 + 31535671 = 31536194
601 + 31535593 = 31536194

Showing the first eight; more decompositions exist.
