Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562702, here are decompositions:

19 + 31562683 = 31562702
79 + 31562623 = 31562702
109 + 31562593 = 31562702
151 + 31562551 = 31562702
271 + 31562431 = 31562702
313 + 31562389 = 31562702
373 + 31562329 = 31562702
421 + 31562281 = 31562702

Showing the first eight; more decompositions exist.
