Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536794, here are decompositions:

61 + 31536733 = 31536794
97 + 31536697 = 31536794
181 + 31536613 = 31536794
313 + 31536481 = 31536794
397 + 31536397 = 31536794
433 + 31536361 = 31536794
571 + 31536223 = 31536794
607 + 31536187 = 31536794

Showing the first eight; more decompositions exist.
