Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576076, here are decompositions:

67 + 31576009 = 31576076
73 + 31576003 = 31576076
139 + 31575937 = 31576076
199 + 31575877 = 31576076
277 + 31575799 = 31576076
283 + 31575793 = 31576076
307 + 31575769 = 31576076
349 + 31575727 = 31576076

Showing the first eight; more decompositions exist.
