Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540450, here are decompositions:

107 + 31540343 = 31540450
233 + 31540217 = 31540450
239 + 31540211 = 31540450
269 + 31540181 = 31540450
419 + 31540031 = 31540450
443 + 31540007 = 31540450
479 + 31539971 = 31540450
587 + 31539863 = 31540450

Showing the first eight; more decompositions exist.
