Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576046, here are decompositions:

37 + 31576009 = 31576046
43 + 31576003 = 31576046
109 + 31575937 = 31576046
223 + 31575823 = 31576046
277 + 31575769 = 31576046
349 + 31575697 = 31576046
379 + 31575667 = 31576046
409 + 31575637 = 31576046

Showing the first eight; more decompositions exist.
