Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499452, here are decompositions:

41 + 31499411 = 31499452
53 + 31499399 = 31499452
263 + 31499189 = 31499452
269 + 31499183 = 31499452
293 + 31499159 = 31499452
389 + 31499063 = 31499452
419 + 31499033 = 31499452
431 + 31499021 = 31499452

Showing the first eight; more decompositions exist.
