Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498052, here are decompositions:

13 + 31498039 = 31498052
43 + 31498009 = 31498052
73 + 31497979 = 31498052
181 + 31497871 = 31498052
193 + 31497859 = 31498052
331 + 31497721 = 31498052
373 + 31497679 = 31498052
379 + 31497673 = 31498052

Showing the first eight; more decompositions exist.
