Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576064, here are decompositions:

61 + 31576003 = 31576064
73 + 31575991 = 31576064
127 + 31575937 = 31576064
241 + 31575823 = 31576064
271 + 31575793 = 31576064
337 + 31575727 = 31576064
367 + 31575697 = 31576064
397 + 31575667 = 31576064

Showing the first eight; more decompositions exist.
