Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472302, here are decompositions:

11 + 31472291 = 31472302
41 + 31472261 = 31472302
101 + 31472201 = 31472302
149 + 31472153 = 31472302
179 + 31472123 = 31472302
233 + 31472069 = 31472302
311 + 31471991 = 31472302
401 + 31471901 = 31472302

Showing the first eight; more decompositions exist.
