Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498412, here are decompositions:

139 + 31498273 = 31498412
199 + 31498213 = 31498412
223 + 31498189 = 31498412
373 + 31498039 = 31498412
409 + 31498003 = 31498412
433 + 31497979 = 31498412
541 + 31497871 = 31498412
661 + 31497751 = 31498412

Showing the first eight; more decompositions exist.
