Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498800, here are decompositions:

37 + 31498763 = 31498800
59 + 31498741 = 31498800
97 + 31498703 = 31498800
241 + 31498559 = 31498800
251 + 31498549 = 31498800
271 + 31498529 = 31498800
283 + 31498517 = 31498800
331 + 31498469 = 31498800

Showing the first eight; more decompositions exist.
