Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472112, here are decompositions:

5 + 31472107 = 31472112
43 + 31472069 = 31472112
59 + 31472053 = 31472112
71 + 31472041 = 31472112
83 + 31472029 = 31472112
101 + 31472011 = 31472112
109 + 31472003 = 31472112
173 + 31471939 = 31472112

Showing the first eight; more decompositions exist.
