Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597802, here are decompositions:

73 + 31597729 = 31597802
109 + 31597693 = 31597802
151 + 31597651 = 31597802
163 + 31597639 = 31597802
199 + 31597603 = 31597802
331 + 31597471 = 31597802
349 + 31597453 = 31597802
541 + 31597261 = 31597802

Showing the first eight; more decompositions exist.
