Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472150, here are decompositions:

7 + 31472143 = 31472150
19 + 31472131 = 31472150
43 + 31472107 = 31472150
97 + 31472053 = 31472150
109 + 31472041 = 31472150
139 + 31472011 = 31472150
211 + 31471939 = 31472150
439 + 31471711 = 31472150

Showing the first eight; more decompositions exist.
