Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473814, here are decompositions:

3 + 31473811 = 31473814
5 + 31473809 = 31473814
107 + 31473707 = 31473814
233 + 31473581 = 31473814
401 + 31473413 = 31473814
563 + 31473251 = 31473814
641 + 31473173 = 31473814
653 + 31473161 = 31473814

Showing the first eight; more decompositions exist.
