Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480250, here are decompositions:

229 + 31480021 = 31480250
421 + 31479829 = 31480250
433 + 31479817 = 31480250
457 + 31479793 = 31480250
601 + 31479649 = 31480250
631 + 31479619 = 31480250
661 + 31479589 = 31480250
673 + 31479577 = 31480250

Showing the first eight; more decompositions exist.
