Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449832, here are decompositions:

41 + 31449791 = 31449832
131 + 31449701 = 31449832
251 + 31449581 = 31449832
263 + 31449569 = 31449832
353 + 31449479 = 31449832
383 + 31449449 = 31449832
431 + 31449401 = 31449832
509 + 31449323 = 31449832

Showing the first eight; more decompositions exist.
