Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476230, here are decompositions:

43 + 31476187 = 31476230
61 + 31476169 = 31476230
73 + 31476157 = 31476230
157 + 31476073 = 31476230
199 + 31476031 = 31476230
277 + 31475953 = 31476230
433 + 31475797 = 31476230
547 + 31475683 = 31476230

Showing the first eight; more decompositions exist.
