Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476572, here are decompositions:

73 + 31476499 = 31476572
139 + 31476433 = 31476572
181 + 31476391 = 31476572
199 + 31476373 = 31476572
223 + 31476349 = 31476572
229 + 31476343 = 31476572
499 + 31476073 = 31476572
541 + 31476031 = 31476572

Showing the first eight; more decompositions exist.
