Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473532, here are decompositions:

3 + 31473529 = 31473532
53 + 31473479 = 31473532
173 + 31473359 = 31473532
269 + 31473263 = 31473532
281 + 31473251 = 31473532
359 + 31473173 = 31473532
449 + 31473083 = 31473532
491 + 31473041 = 31473532

Showing the first eight; more decompositions exist.
