Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472582, here are decompositions:

103 + 31472479 = 31472582
223 + 31472359 = 31472582
373 + 31472209 = 31472582
433 + 31472149 = 31472582
439 + 31472143 = 31472582
541 + 31472041 = 31472582
571 + 31472011 = 31472582
643 + 31471939 = 31472582

Showing the first eight; more decompositions exist.
