Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536774, here are decompositions:

41 + 31536733 = 31536774
43 + 31536731 = 31536774
67 + 31536707 = 31536774
167 + 31536607 = 31536774
223 + 31536551 = 31536774
293 + 31536481 = 31536774
383 + 31536391 = 31536774
421 + 31536353 = 31536774

Showing the first eight; more decompositions exist.
