Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496378, here are decompositions:

7 + 31496371 = 31496378
61 + 31496317 = 31496378
157 + 31496221 = 31496378
337 + 31496041 = 31496378
367 + 31496011 = 31496378
457 + 31495921 = 31496378
499 + 31495879 = 31496378
577 + 31495801 = 31496378

Showing the first eight; more decompositions exist.
