Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593098, here are decompositions:

67 + 31593031 = 31593098
127 + 31592971 = 31593098
139 + 31592959 = 31593098
151 + 31592947 = 31593098
337 + 31592761 = 31593098
421 + 31592677 = 31593098
457 + 31592641 = 31593098
499 + 31592599 = 31593098

Showing the first eight; more decompositions exist.
