Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472546, here are decompositions:

67 + 31472479 = 31472546
97 + 31472449 = 31472546
109 + 31472437 = 31472546
307 + 31472239 = 31472546
337 + 31472209 = 31472546
367 + 31472179 = 31472546
379 + 31472167 = 31472546
397 + 31472149 = 31472546

Showing the first eight; more decompositions exist.
