Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472260, here are decompositions:

59 + 31472201 = 31472260
101 + 31472159 = 31472260
107 + 31472153 = 31472260
137 + 31472123 = 31472260
191 + 31472069 = 31472260
257 + 31472003 = 31472260
269 + 31471991 = 31472260
293 + 31471967 = 31472260

Showing the first eight; more decompositions exist.
