Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472632, here are decompositions:

41 + 31472591 = 31472632
131 + 31472501 = 31472632
281 + 31472351 = 31472632
293 + 31472339 = 31472632
431 + 31472201 = 31472632
449 + 31472183 = 31472632
479 + 31472153 = 31472632
509 + 31472123 = 31472632

Showing the first eight; more decompositions exist.
