Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498424, here are decompositions:

3 + 31498421 = 31498424
151 + 31498273 = 31498424
211 + 31498213 = 31498424
313 + 31498111 = 31498424
337 + 31498087 = 31498424
421 + 31498003 = 31498424
541 + 31497883 = 31498424
673 + 31497751 = 31498424

Showing the first eight; more decompositions exist.
