Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541820, here are decompositions:

59 + 31541761 = 31541820
83 + 31541737 = 31541820
113 + 31541707 = 31541820
127 + 31541693 = 31541820
223 + 31541597 = 31541820
229 + 31541591 = 31541820
239 + 31541581 = 31541820
251 + 31541569 = 31541820

Showing the first eight; more decompositions exist.
