Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498342, here are decompositions:

53 + 31498289 = 31498342
89 + 31498253 = 31498342
149 + 31498193 = 31498342
191 + 31498151 = 31498342
401 + 31497941 = 31498342
479 + 31497863 = 31498342
569 + 31497773 = 31498342
641 + 31497701 = 31498342

Showing the first eight; more decompositions exist.
