Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502174, here are decompositions:

13 + 31502161 = 31502174
43 + 31502131 = 31502174
61 + 31502113 = 31502174
313 + 31501861 = 31502174
367 + 31501807 = 31502174
433 + 31501741 = 31502174
541 + 31501633 = 31502174
607 + 31501567 = 31502174

Showing the first eight; more decompositions exist.
