Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462792, here are decompositions:

41 + 31462751 = 31462792
239 + 31462553 = 31462792
311 + 31462481 = 31462792
353 + 31462439 = 31462792
359 + 31462433 = 31462792
419 + 31462373 = 31462792
443 + 31462349 = 31462792
479 + 31462313 = 31462792

Showing the first eight; more decompositions exist.
