Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498912, here are decompositions:

59 + 31498853 = 31498912
83 + 31498829 = 31498912
101 + 31498811 = 31498912
149 + 31498763 = 31498912
353 + 31498559 = 31498912
383 + 31498529 = 31498912
443 + 31498469 = 31498912
449 + 31498463 = 31498912

Showing the first eight; more decompositions exist.
