Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613542, here are decompositions:

3 + 31613539 = 31613542
29 + 31613513 = 31613542
101 + 31613441 = 31613542
131 + 31613411 = 31613542
251 + 31613291 = 31613542
293 + 31613249 = 31613542
809 + 31612733 = 31613542
881 + 31612661 = 31613542

Showing the first eight; more decompositions exist.
