Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502598, here are decompositions:

11 + 31502587 = 31502598
37 + 31502561 = 31502598
41 + 31502557 = 31502598
59 + 31502539 = 31502598
109 + 31502489 = 31502598
139 + 31502459 = 31502598
157 + 31502441 = 31502598
167 + 31502431 = 31502598

Showing the first eight; more decompositions exist.
