Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472708, here are decompositions:

97 + 31472611 = 31472708
229 + 31472479 = 31472708
271 + 31472437 = 31472708
349 + 31472359 = 31472708
499 + 31472209 = 31472708
541 + 31472167 = 31472708
577 + 31472131 = 31472708
601 + 31472107 = 31472708

Showing the first eight; more decompositions exist.
