Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562086, here are decompositions:

29 + 31562057 = 31562086
53 + 31562033 = 31562086
113 + 31561973 = 31562086
167 + 31561919 = 31562086
239 + 31561847 = 31562086
263 + 31561823 = 31562086
389 + 31561697 = 31562086
443 + 31561643 = 31562086

Showing the first eight; more decompositions exist.
