Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488674, here are decompositions:

43 + 31488631 = 31488674
127 + 31488547 = 31488674
181 + 31488493 = 31488674
193 + 31488481 = 31488674
211 + 31488463 = 31488674
241 + 31488433 = 31488674
463 + 31488211 = 31488674
541 + 31488133 = 31488674

Showing the first eight; more decompositions exist.
