Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472174, here are decompositions:

7 + 31472167 = 31472174
31 + 31472143 = 31472174
43 + 31472131 = 31472174
67 + 31472107 = 31472174
163 + 31472011 = 31472174
241 + 31471933 = 31472174
463 + 31471711 = 31472174
541 + 31471633 = 31472174

Showing the first eight; more decompositions exist.
