Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623342, here are decompositions:

5 + 31623337 = 31623342
131 + 31623211 = 31623342
173 + 31623169 = 31623342
229 + 31623113 = 31623342
281 + 31623061 = 31623342
383 + 31622959 = 31623342
409 + 31622933 = 31623342
419 + 31622923 = 31623342

Showing the first eight; more decompositions exist.
