Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540852, here are decompositions:

29 + 31540823 = 31540852
173 + 31540679 = 31540852
353 + 31540499 = 31540852
359 + 31540493 = 31540852
509 + 31540343 = 31540852
641 + 31540211 = 31540852
743 + 31540109 = 31540852
821 + 31540031 = 31540852

Showing the first eight; more decompositions exist.
