Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472954, here are decompositions:

67 + 31472887 = 31472954
103 + 31472851 = 31472954
127 + 31472827 = 31472954
181 + 31472773 = 31472954
367 + 31472587 = 31472954
661 + 31472293 = 31472954
787 + 31472167 = 31472954
811 + 31472143 = 31472954

Showing the first eight; more decompositions exist.
