Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473562, here are decompositions:

83 + 31473479 = 31473562
149 + 31473413 = 31473562
311 + 31473251 = 31473562
353 + 31473209 = 31473562
359 + 31473203 = 31473562
389 + 31473173 = 31473562
401 + 31473161 = 31473562
479 + 31473083 = 31473562

Showing the first eight; more decompositions exist.
