Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498070, here are decompositions:

31 + 31498039 = 31498070
61 + 31498009 = 31498070
67 + 31498003 = 31498070
73 + 31497997 = 31498070
139 + 31497931 = 31498070
199 + 31497871 = 31498070
211 + 31497859 = 31498070
313 + 31497757 = 31498070

Showing the first eight; more decompositions exist.
