Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450796, here are decompositions:

7 + 31450789 = 31450796
73 + 31450723 = 31450796
193 + 31450603 = 31450796
313 + 31450483 = 31450796
367 + 31450429 = 31450796
373 + 31450423 = 31450796
409 + 31450387 = 31450796
577 + 31450219 = 31450796

Showing the first eight; more decompositions exist.
