Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479852, here are decompositions:

23 + 31479829 = 31479852
31 + 31479821 = 31479852
59 + 31479793 = 31479852
83 + 31479769 = 31479852
109 + 31479743 = 31479852
113 + 31479739 = 31479852
181 + 31479671 = 31479852
233 + 31479619 = 31479852

Showing the first eight; more decompositions exist.
