Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482536, here are decompositions:

37 + 31482499 = 31482536
97 + 31482439 = 31482536
109 + 31482427 = 31482536
193 + 31482343 = 31482536
199 + 31482337 = 31482536
229 + 31482307 = 31482536
307 + 31482229 = 31482536
367 + 31482169 = 31482536

Showing the first eight; more decompositions exist.
