Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498754, here are decompositions:

13 + 31498741 = 31498754
97 + 31498657 = 31498754
163 + 31498591 = 31498754
241 + 31498513 = 31498754
283 + 31498471 = 31498754
541 + 31498213 = 31498754
631 + 31498123 = 31498754
643 + 31498111 = 31498754

Showing the first eight; more decompositions exist.
