Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472558, here are decompositions:

79 + 31472479 = 31472558
109 + 31472449 = 31472558
199 + 31472359 = 31472558
349 + 31472209 = 31472558
367 + 31472191 = 31472558
379 + 31472179 = 31472558
409 + 31472149 = 31472558
547 + 31472011 = 31472558

Showing the first eight; more decompositions exist.
