Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484762, here are decompositions:

193 + 31484569 = 31484762
229 + 31484533 = 31484762
313 + 31484449 = 31484762
349 + 31484413 = 31484762
409 + 31484353 = 31484762
523 + 31484239 = 31484762
601 + 31484161 = 31484762
619 + 31484143 = 31484762

Showing the first eight; more decompositions exist.
