Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498646, here are decompositions:

7 + 31498639 = 31498646
97 + 31498549 = 31498646
367 + 31498279 = 31498646
373 + 31498273 = 31498646
433 + 31498213 = 31498646
457 + 31498189 = 31498646
523 + 31498123 = 31498646
577 + 31498069 = 31498646

Showing the first eight; more decompositions exist.
