Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524890, here are decompositions:

97 + 31524793 = 31524890
127 + 31524763 = 31524890
283 + 31524607 = 31524890
349 + 31524541 = 31524890
367 + 31524523 = 31524890
373 + 31524517 = 31524890
421 + 31524469 = 31524890
487 + 31524403 = 31524890

Showing the first eight; more decompositions exist.
