Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506292, here are decompositions:

29 + 31506263 = 31506292
173 + 31506119 = 31506292
263 + 31506029 = 31506292
353 + 31505939 = 31506292
383 + 31505909 = 31506292
449 + 31505843 = 31506292
479 + 31505813 = 31506292
491 + 31505801 = 31506292

Showing the first eight; more decompositions exist.
