Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488524, here are decompositions:

31 + 31488493 = 31488524
43 + 31488481 = 31488524
61 + 31488463 = 31488524
313 + 31488211 = 31488524
433 + 31488091 = 31488524
547 + 31487977 = 31488524
607 + 31487917 = 31488524
877 + 31487647 = 31488524

Showing the first eight; more decompositions exist.
