Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502622, here are decompositions:

59 + 31502563 = 31502622
61 + 31502561 = 31502622
83 + 31502539 = 31502622
89 + 31502533 = 31502622
139 + 31502483 = 31502622
163 + 31502459 = 31502622
181 + 31502441 = 31502622
191 + 31502431 = 31502622

Showing the first eight; more decompositions exist.
