Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473272, here are decompositions:

31 + 31473241 = 31473272
109 + 31473163 = 31473272
163 + 31473109 = 31473272
211 + 31473061 = 31473272
241 + 31473031 = 31473272
421 + 31472851 = 31473272
433 + 31472839 = 31473272
499 + 31472773 = 31473272

Showing the first eight; more decompositions exist.
