Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542654, here are decompositions:

23 + 31542631 = 31542654
41 + 31542613 = 31542654
67 + 31542587 = 31542654
107 + 31542547 = 31542654
131 + 31542523 = 31542654
167 + 31542487 = 31542654
197 + 31542457 = 31542654
257 + 31542397 = 31542654

Showing the first eight; more decompositions exist.
