Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475572, here are decompositions:

83 + 31475489 = 31475572
101 + 31475471 = 31475572
113 + 31475459 = 31475572
179 + 31475393 = 31475572
251 + 31475321 = 31475572
383 + 31475189 = 31475572
431 + 31475141 = 31475572
461 + 31475111 = 31475572

Showing the first eight; more decompositions exist.
