Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472964, here are decompositions:

37 + 31472927 = 31472964
73 + 31472891 = 31472964
97 + 31472867 = 31472964
113 + 31472851 = 31472964
137 + 31472827 = 31472964
151 + 31472813 = 31472964
157 + 31472807 = 31472964
191 + 31472773 = 31472964

Showing the first eight; more decompositions exist.
