Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496072, here are decompositions:

31 + 31496041 = 31496072
61 + 31496011 = 31496072
151 + 31495921 = 31496072
193 + 31495879 = 31496072
271 + 31495801 = 31496072
331 + 31495741 = 31496072
379 + 31495693 = 31496072
409 + 31495663 = 31496072

Showing the first eight; more decompositions exist.
