Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540262, here are decompositions:

73 + 31540189 = 31540262
139 + 31540123 = 31540262
163 + 31540099 = 31540262
199 + 31540063 = 31540262
331 + 31539931 = 31540262
373 + 31539889 = 31540262
499 + 31539763 = 31540262
601 + 31539661 = 31540262

Showing the first eight; more decompositions exist.
