Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498634, here are decompositions:

43 + 31498591 = 31498634
163 + 31498471 = 31498634
421 + 31498213 = 31498634
523 + 31498111 = 31498634
547 + 31498087 = 31498634
631 + 31498003 = 31498634
751 + 31497883 = 31498634
877 + 31497757 = 31498634

Showing the first eight; more decompositions exist.
