Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463242, here are decompositions:

29 + 31463213 = 31463242
179 + 31463063 = 31463242
263 + 31462979 = 31463242
311 + 31462931 = 31463242
353 + 31462889 = 31463242
431 + 31462811 = 31463242
449 + 31462793 = 31463242
491 + 31462751 = 31463242

Showing the first eight; more decompositions exist.
