Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540414, here are decompositions:

71 + 31540343 = 31540414
173 + 31540241 = 31540414
197 + 31540217 = 31540414
233 + 31540181 = 31540414
251 + 31540163 = 31540414
383 + 31540031 = 31540414
401 + 31540013 = 31540414
443 + 31539971 = 31540414

Showing the first eight; more decompositions exist.
