Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498394, here are decompositions:

181 + 31498213 = 31498394
271 + 31498123 = 31498394
283 + 31498111 = 31498394
307 + 31498087 = 31498394
397 + 31497997 = 31498394
463 + 31497931 = 31498394
523 + 31497871 = 31498394
643 + 31497751 = 31498394

Showing the first eight; more decompositions exist.
