Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472498, here are decompositions:

19 + 31472479 = 31472498
61 + 31472437 = 31472498
139 + 31472359 = 31472498
307 + 31472191 = 31472498
331 + 31472167 = 31472498
349 + 31472149 = 31472498
367 + 31472131 = 31472498
457 + 31472041 = 31472498

Showing the first eight; more decompositions exist.
