Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576364, here are decompositions:

13 + 31576351 = 31576364
97 + 31576267 = 31576364
103 + 31576261 = 31576364
163 + 31576201 = 31576364
277 + 31576087 = 31576364
373 + 31575991 = 31576364
487 + 31575877 = 31576364
541 + 31575823 = 31576364

Showing the first eight; more decompositions exist.
