Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536830, here are decompositions:

7 + 31536823 = 31536830
37 + 31536793 = 31536830
97 + 31536733 = 31536830
223 + 31536607 = 31536830
331 + 31536499 = 31536830
349 + 31536481 = 31536830
433 + 31536397 = 31536830
439 + 31536391 = 31536830

Showing the first eight; more decompositions exist.
