Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506232, here are decompositions:

59 + 31506173 = 31506232
83 + 31506149 = 31506232
113 + 31506119 = 31506232
239 + 31505993 = 31506232
293 + 31505939 = 31506232
311 + 31505921 = 31506232
389 + 31505843 = 31506232
419 + 31505813 = 31506232

Showing the first eight; more decompositions exist.
