Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523998, here are decompositions:

59 + 31523939 = 31523998
197 + 31523801 = 31523998
347 + 31523651 = 31523998
419 + 31523579 = 31523998
461 + 31523537 = 31523998
521 + 31523477 = 31523998
557 + 31523441 = 31523998
587 + 31523411 = 31523998

Showing the first eight; more decompositions exist.
