Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498084, here are decompositions:

41 + 31498043 = 31498084
257 + 31497827 = 31498084
281 + 31497803 = 31498084
311 + 31497773 = 31498084
347 + 31497737 = 31498084
383 + 31497701 = 31498084
557 + 31497527 = 31498084
593 + 31497491 = 31498084

Showing the first eight; more decompositions exist.
