Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540702, here are decompositions:

3 + 31540699 = 31540702
23 + 31540679 = 31540702
59 + 31540643 = 31540702
71 + 31540631 = 31540702
173 + 31540529 = 31540702
359 + 31540343 = 31540702
461 + 31540241 = 31540702
491 + 31540211 = 31540702

Showing the first eight; more decompositions exist.
