Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474132, here are decompositions:

3 + 31474129 = 31474132
59 + 31474073 = 31474132
71 + 31474061 = 31474132
89 + 31474043 = 31474132
269 + 31473863 = 31474132
293 + 31473839 = 31474132
353 + 31473779 = 31474132
653 + 31473479 = 31474132

Showing the first eight; more decompositions exist.
