Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472062, here are decompositions:

59 + 31472003 = 31472062
71 + 31471991 = 31472062
179 + 31471883 = 31472062
239 + 31471823 = 31472062
263 + 31471799 = 31472062
359 + 31471703 = 31472062
593 + 31471469 = 31472062
701 + 31471361 = 31472062

Showing the first eight; more decompositions exist.
