Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498848, here are decompositions:

11 + 31498837 = 31498848
19 + 31498829 = 31498848
37 + 31498811 = 31498848
107 + 31498741 = 31498848
191 + 31498657 = 31498848
257 + 31498591 = 31498848
307 + 31498541 = 31498848
331 + 31498517 = 31498848

Showing the first eight; more decompositions exist.
