Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461598, here are decompositions:

29 + 31461569 = 31461598
41 + 31461557 = 31461598
257 + 31461341 = 31461598
317 + 31461281 = 31461598
419 + 31461179 = 31461598
449 + 31461149 = 31461598
587 + 31461011 = 31461598
647 + 31460951 = 31461598

Showing the first eight; more decompositions exist.
