Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487024, here are decompositions:

3 + 31487021 = 31487024
43 + 31486981 = 31487024
97 + 31486927 = 31487024
313 + 31486711 = 31487024
367 + 31486657 = 31487024
397 + 31486627 = 31487024
421 + 31486603 = 31487024
487 + 31486537 = 31487024

Showing the first eight; more decompositions exist.
