Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495524, here are decompositions:

7 + 31495517 = 31495524
13 + 31495511 = 31495524
23 + 31495501 = 31495524
31 + 31495493 = 31495524
43 + 31495481 = 31495524
61 + 31495463 = 31495524
101 + 31495423 = 31495524
107 + 31495417 = 31495524

Showing the first eight; more decompositions exist.
