Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472060, here are decompositions:

7 + 31472053 = 31472060
19 + 31472041 = 31472060
31 + 31472029 = 31472060
127 + 31471933 = 31472060
211 + 31471849 = 31472060
229 + 31471831 = 31472060
349 + 31471711 = 31472060
379 + 31471681 = 31472060

Showing the first eight; more decompositions exist.
