Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480394, here are decompositions:

3 + 31480391 = 31480394
13 + 31480381 = 31480394
193 + 31480201 = 31480394
277 + 31480117 = 31480394
373 + 31480021 = 31480394
433 + 31479961 = 31480394
577 + 31479817 = 31480394
601 + 31479793 = 31480394

Showing the first eight; more decompositions exist.
