Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460998, here are decompositions:

47 + 31460951 = 31460998
71 + 31460927 = 31460998
167 + 31460831 = 31460998
269 + 31460729 = 31460998
281 + 31460717 = 31460998
389 + 31460609 = 31460998
449 + 31460549 = 31460998
461 + 31460537 = 31460998

Showing the first eight; more decompositions exist.
