Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480562, here are decompositions:

181 + 31480381 = 31480562
193 + 31480369 = 31480562
433 + 31480129 = 31480562
541 + 31480021 = 31480562
601 + 31479961 = 31480562
613 + 31479949 = 31480562
733 + 31479829 = 31480562
769 + 31479793 = 31480562

Showing the first eight; more decompositions exist.
