Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480036, here are decompositions:

17 + 31480019 = 31480036
89 + 31479947 = 31480036
179 + 31479857 = 31480036
233 + 31479803 = 31480036
293 + 31479743 = 31480036
317 + 31479719 = 31480036
389 + 31479647 = 31480036
443 + 31479593 = 31480036

Showing the first eight; more decompositions exist.
