Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576526, here are decompositions:

43 + 31576483 = 31576526
67 + 31576459 = 31576526
73 + 31576453 = 31576526
109 + 31576417 = 31576526
307 + 31576219 = 31576526
409 + 31576117 = 31576526
439 + 31576087 = 31576526
523 + 31576003 = 31576526

Showing the first eight; more decompositions exist.
