Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473236, here are decompositions:

19 + 31473217 = 31473236
73 + 31473163 = 31473236
127 + 31473109 = 31473236
199 + 31473037 = 31473236
307 + 31472929 = 31473236
349 + 31472887 = 31473236
397 + 31472839 = 31473236
409 + 31472827 = 31473236

Showing the first eight; more decompositions exist.
