Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473284, here are decompositions:

43 + 31473241 = 31473284
67 + 31473217 = 31473284
97 + 31473187 = 31473284
223 + 31473061 = 31473284
397 + 31472887 = 31473284
433 + 31472851 = 31473284
457 + 31472827 = 31473284
673 + 31472611 = 31473284

Showing the first eight; more decompositions exist.
