Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576226, here are decompositions:

7 + 31576219 = 31576226
109 + 31576117 = 31576226
139 + 31576087 = 31576226
223 + 31576003 = 31576226
349 + 31575877 = 31576226
397 + 31575829 = 31576226
433 + 31575793 = 31576226
457 + 31575769 = 31576226

Showing the first eight; more decompositions exist.
