Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465772, here are decompositions:

31 + 31465741 = 31465772
61 + 31465711 = 31465772
109 + 31465663 = 31465772
193 + 31465579 = 31465772
211 + 31465561 = 31465772
313 + 31465459 = 31465772
409 + 31465363 = 31465772
463 + 31465309 = 31465772

Showing the first eight; more decompositions exist.
