Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562762, here are decompositions:

79 + 31562683 = 31562762
139 + 31562623 = 31562762
151 + 31562611 = 31562762
211 + 31562551 = 31562762
313 + 31562449 = 31562762
331 + 31562431 = 31562762
373 + 31562389 = 31562762
433 + 31562329 = 31562762

Showing the first eight; more decompositions exist.
