Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481074, here are decompositions:

17 + 31481057 = 31481074
101 + 31480973 = 31481074
173 + 31480901 = 31481074
281 + 31480793 = 31481074
311 + 31480763 = 31481074
641 + 31480433 = 31481074
683 + 31480391 = 31481074
701 + 31480373 = 31481074

Showing the first eight; more decompositions exist.
