Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540598, here are decompositions:

97 + 31540501 = 31540598
109 + 31540489 = 31540598
127 + 31540471 = 31540598
157 + 31540441 = 31540598
181 + 31540417 = 31540598
337 + 31540261 = 31540598
409 + 31540189 = 31540598
499 + 31540099 = 31540598

Showing the first eight; more decompositions exist.
