Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487062, here are decompositions:

29 + 31487033 = 31487062
41 + 31487021 = 31487062
293 + 31486769 = 31487062
311 + 31486751 = 31487062
353 + 31486709 = 31487062
401 + 31486661 = 31487062
419 + 31486643 = 31487062
449 + 31486613 = 31487062

Showing the first eight; more decompositions exist.
