Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472612, here are decompositions:

163 + 31472449 = 31472612
373 + 31472239 = 31472612
421 + 31472191 = 31472612
433 + 31472179 = 31472612
463 + 31472149 = 31472612
571 + 31472041 = 31472612
601 + 31472011 = 31472612
673 + 31471939 = 31472612

Showing the first eight; more decompositions exist.
