Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576062, here are decompositions:

13 + 31576049 = 31576062
31 + 31576031 = 31576062
53 + 31576009 = 31576062
59 + 31576003 = 31576062
61 + 31576001 = 31576062
71 + 31575991 = 31576062
139 + 31575923 = 31576062
163 + 31575899 = 31576062

Showing the first eight; more decompositions exist.
