Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480074, here are decompositions:

13 + 31480061 = 31480074
53 + 31480021 = 31480074
113 + 31479961 = 31480074
127 + 31479947 = 31480074
193 + 31479881 = 31480074
257 + 31479817 = 31480074
271 + 31479803 = 31480074
281 + 31479793 = 31480074

Showing the first eight; more decompositions exist.
