Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498948, here are decompositions:

17 + 31498931 = 31498948
101 + 31498847 = 31498948
137 + 31498811 = 31498948
389 + 31498559 = 31498948
401 + 31498547 = 31498948
419 + 31498529 = 31498948
431 + 31498517 = 31498948
449 + 31498499 = 31498948

Showing the first eight; more decompositions exist.
