Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593860, here are decompositions:

73 + 31593787 = 31593860
97 + 31593763 = 31593860
139 + 31593721 = 31593860
157 + 31593703 = 31593860
229 + 31593631 = 31593860
271 + 31593589 = 31593860
307 + 31593553 = 31593860
349 + 31593511 = 31593860

Showing the first eight; more decompositions exist.
